A
Action
Definition: Action is money wagered on a game or market.
You will also hear bettors say they “want action,” which simply means they want a bet on the game.
Against the Spread (ATS)
Definition: ATS means a team’s record against the point spread, not its outright win-loss record.
If a team is 6-3 ATS, it has covered the spread six times in nine games.
Alternate Line
Definition: An alternate line is a non-standard spread or total with adjusted odds.
A sportsbook may offer -2.5, -3.5, and -6.5 on the same game, each with a different price.
American Odds
Definition: American odds use plus and minus numbers to show payout and risk.
Negative odds show how much you need to risk to win $100, while positive odds show how much profit you make on a $100 bet.
Asian Handicap
Definition: Asian handicap is a soccer market that removes or reduces the draw by giving one side a handicap.
Some Asian handicap lines use quarter goals such as -0.25 or +0.75, which can split your stake into two parts.
B
Backdoor Cover
Definition: A backdoor cover happens when a late score lets a team cover the spread after the bet looked dead.
A team losing by 14 may score in the final minute and lose by 7, which can still cash +7.5.
Bad Beat
Definition: A bad beat is a painful loss on a bet that looked likely to win for most of the game.
Late fouls, garbage-time scores, and overtime are common causes of bad beats.
Bankroll
Definition: Your bankroll is the total amount of money you set aside only for betting.
I always treat bankroll money as separate from rent, bills, and daily spending.
Bet Slip
Definition: A bet slip is the screen or ticket that shows your selections, stake, odds, and potential payout.
Before placing any bet, check the bet slip for line changes, the right market, and the correct stake.
Bonus Bet
Definition: A bonus bet is promotional credit given by a sportsbook, usually after a signup offer or special campaign.
Bonus bets often come with rules on where they can be used and whether the stake is returned on a win.
Book / Bookie / Bookmaker
Definition: A book, bookie, or bookmaker is the operator that sets odds and accepts bets.
On modern apps, “book” usually refers to the sportsbook itself rather than a person taking bets by phone.
Both Teams to Score (BTTS)
Definition: BTTS is a soccer market on whether both teams will score at least one goal.
If one team wins 2-0, BTTS loses because both teams did not score.
Buying Points
Definition: Buying points means paying extra vig to move the spread or total in your favor.
For example, you may move -3.5 to -3, but the better number usually comes with a worse price.
C
Cash Out
Definition: Cash out lets you settle a bet before the event ends for its current value.
It can reduce risk, but I never treat it as automatic value because the offer is often priced in the sportsbook’s favor.
Chalk
Definition: Chalk is slang for the favorite, especially a strong favorite.
If a bettor says they do not like laying chalk, they mean they do not like betting heavily favored teams at short prices.
Closing Line
Definition: The closing line is the last widely available line before the market closes at game time.
Many bettors compare their ticket to the closing line to judge whether they got a strong number.
Closing Line Value (CLV)
Definition: CLV means you placed a bet at a better price or number than the closing line.
If you bet +4.5 and the market closes +3, you beat the closing line even before the game starts.
Cover
Definition: To cover means a team beats the spread result needed for your bet to win.
A favorite covers by winning by enough, while an underdog covers by staying within the number or winning outright.
D
Decimal Odds
Definition: Decimal odds show your total return as a multiplier of your stake.
Odds of 2.50 mean a $100 bet returns $250 total, including your original $100 stake.
Dog
Definition: Dog is short for underdog.
If a bettor says they like the dog, they mean they are taking the less favored side.
Draw No Bet
Definition: Draw no bet is a soccer market where your stake is refunded if the match ends in a draw.
It is a simpler option for beginners who want to back one side without losing to a tied result.
E
Edge
Definition: Edge is the advantage you believe you have over the sportsbook’s price.
If I think a team should be priced shorter than the odds on screen, I believe I have an edge on that bet.
Even Money
Definition: Even money means a winning bet pays profit equal to your stake.
In American odds that is usually +100, and in decimal odds it is 2.00.
Expected Value (EV)
Definition: Expected value measures whether a bet looks profitable in the long run based on your estimate of the true odds.
Positive EV does not guarantee this ticket wins, but it suggests the price is better than the real risk.
F
Fade
Definition: To fade means to bet against a team, bettor, or popular opinion.
Some bettors like to fade public sides or fade hype when a line looks inflated.
Favorite
Definition: The favorite is the side expected to win.
Favorites usually have negative odds such as -140 or -220.
Fractional Odds
Definition: Fractional odds are a common UK format written as fractions such as 5/2 or 10/1.
At 5/2, you win $250 in profit for every $100 staked.
Free Bet
Definition: A free bet is promotional credit that can be used on an eligible market.
Many books return profit only on free bets, which means you often do not get the free stake back on a win.
Futures
Definition: Futures are long-term bets on outcomes decided later in the season.
Common examples include championship winners, division winners, MVP awards, and team win totals.
H
Handle
Definition: Handle is the total amount wagered by customers.
If a book takes $500,000 in bets on one game, that full amount is the handle.
Hedge
Definition: Hedging means placing another bet on the opposite side to reduce risk or lock in part of a profit.
I usually check the math first, because some hedges protect your nerves more than your value.
Hold
Definition: Hold is the percentage of total wagers the sportsbook keeps after paying winners.
It is a business metric for the book, not the same thing as your personal win rate.
Hook
Definition: The hook is the half-point attached to a spread or total, such as -3.5 or 47.5.
That half-point matters because it removes the chance of a push, and in football it can be a big deal around key numbers like 3 and 7.
House Rules
Definition: House rules explain how a sportsbook grades bets, handles cancellations, and applies market limits or bonus terms.
Beginners skip this too often, then get surprised by rules on postponed games, player props, or withdrawals.
I
Implied Probability
Definition: Implied probability converts betting odds into a percentage chance.
For example, +200 implies about 33.3%, while -110 implies about 52.4% before you adjust for vig.
J
Juice / Vig
Definition: Juice, also called vig, is the sportsbook’s built-in fee on a market.
A standard spread priced at -110 on both sides includes that fee.
K
Key Number
Definition: A key number is a common winning margin that shows up often in a sport, especially 3 and 7 in NFL betting.
That is why the difference between -3 and -3.5 matters much more than many beginners expect.
L
Limit
Definition: A limit is the minimum or maximum amount a sportsbook will accept on a bet.
Limits can vary by sport, market, account status, and time of day.
Line Movement
Definition: Line movement is any change in the spread, total, or odds after the opening line is posted.
Lines move because of injuries, news, weather, betting volume, and sportsbook risk management.
Line Shopping
Definition: Line shopping means comparing odds across sportsbooks to find the best available price or number.
Getting +3.5 instead of +3 or -105 instead of -110 can make a real difference over time.
Live Betting
Definition: Live betting means placing wagers after a game has already started.
The odds update in real time, which creates opportunity but also punishes rushed decisions.
M
Market
Definition: A market is a specific betting option offered by the sportsbook.
Moneyline, total, player passing yards, and first team to score are all separate markets.
Moneyline
Definition: A moneyline bet is a wager on which team or player wins outright.
There is no spread involved, which is why moneyline is usually the easiest bet type for beginners.
N
No Action
Definition: No action means a bet was voided and your stake is returned.
This can happen when a game is canceled, a listed pitcher changes, or a market is removed under house rules.
O
Odds Boost
Definition: An odds boost is a promotional increase in the price on a selected market.
It can improve value, but I still compare the boosted line with the normal market before betting it.
Opening Line
Definition: The opening line is the first number a sportsbook posts for a game or market.
Comparing the opening line with the closing line helps you see how the market moved.
Over
Definition: Over is a bet that the total points, runs, goals, or another stat will finish above the posted number.
If the total is 47.5, the over wins at 48 or more.
P
Parlay
Definition: A parlay combines two or more bets into one ticket, and every leg must win.
The payout is higher than a straight bet, but one loss kills the entire ticket.
Payout / Return
Definition: Payout, also called return, is the full amount paid back on a winning bet, including your original stake.
If you stake $50 at +150, your profit is $75 and your total payout or return is $125.
Pick
Definition: A pick is simply a selection or side you choose to bet on.
If I say my pick is the Knicks +4.5, that is the team and line I chose.
Pick’em
Definition: Pick’em means a matchup is priced as essentially even, with no real favorite on the spread.
You will often see it written as PK or pick.
Point Spread
Definition: A point spread is a handicap used to make both sides of a matchup more even for betting purposes.
If a team is -6.5, it must win by 7 or more to cover.
Prop Bet
Definition: A prop bet is a wager on a specific event within a game rather than just the final winner.
Player yards, first touchdown scorer, and team total points are all common props.
Puck Line
Definition: The puck line is the standard hockey spread, usually set at -1.5 and +1.5 goals.
A favorite on the puck line must win by 2 or more goals to cash.
Public Money
Definition: Public money refers to bets from the general betting crowd rather than from respected professional bettors.
Public action often clusters around favorites, big-name teams, and overs.
Push
Definition: A push happens when the final result lands exactly on the betting line, so the bet is refunded.
If you bet Under 42 and the game lands on 42, that is a push.
R
Rollover / Wagering Requirement
Definition: Rollover is the amount you must wager before bonus-related funds become eligible for withdrawal.
A 10x rollover on a $100 bonus usually means you need $1,000 in qualifying wagers before cashing out bonus-linked value.
Round Robin
Definition: A round robin breaks several selections into multiple smaller parlays.
It gives you more ways to cash than one large parlay, but it also costs more because you are placing several bets at once.
Run Line
Definition: The run line is the standard baseball spread, usually set at -1.5 and +1.5 runs.
A baseball favorite on the run line must win by 2 or more runs.
S
Same-Game Parlay
Definition: A same-game parlay combines multiple bets from one event into a single ticket.
The format is popular because the payout can grow fast, but the price is usually less friendly than it looks.
Sharp / Sharp Money
Definition: A sharp is a respected bettor whose action the market takes seriously.
When people say sharp money hit one side, they mean skilled bettors likely helped move the line.
Stake
Definition: Your stake is the amount of money you risk on a bet.
Stake is your original wager, not your profit.
Straight Bet
Definition: A straight bet is one single wager on one market.
A moneyline, spread, or total played by itself is a straight bet.
Straight Up (SU)
Definition: Straight up refers to the outright winner with no spread involved.
A team can win straight up and still fail to cover the spread.
T
Teaser
Definition: A teaser is a parlay that lets you move the spread or total in your favor on each leg for a lower payout.
It sounds safer because of the better numbers, but the price still matters.
Team Total
Definition: A team total is a bet on how many points, runs, or goals one team will score by itself.
You are betting only that team’s output, not the full game total.
Ticket
Definition: A ticket is the record of your bet after it is placed.
Digital sportsbooks show it in your open bets or settled bets section.
Total
Definition: A total is the posted combined score or stat number used for over and under betting.
Full-game points, first-half points, and player assists can all have totals.
U
Under
Definition: Under is a bet that the total points, runs, goals, or another stat will finish below the posted number.
If the total is 47.5, the under wins at 47 or fewer.
Underdog
Definition: The underdog is the side expected to lose.
Underdogs usually have positive odds such as +120 or +180.
Unit
Definition: A unit is your standard bet size, used to keep staking consistent.
Many bettors use 1 unit as about 1% to 2% of bankroll, though the exact size depends on risk tolerance.
V
Value Bet
Definition: A value bet is a wager where the sportsbook’s odds are better than your estimate of the true probability.
Finding value matters more in the long run than simply picking the team you think wins most often.
W
Wager
Definition: Wager is another word for a bet.
Sportsbooks use this word constantly in house rules, bonus terms, and betting menus, so beginners should get comfortable seeing wager and bet used interchangeably.
Withdrawal
Definition: A withdrawal is the process of taking money out of your sportsbook account.
Before requesting one, I always check the method, timing, fees, and any verification rules.
Win Total
Definition: A win total is a futures market on how many games a team will win during the season.
You usually bet the over or under on a posted number such as 8.5 wins.
Where Beginners Usually Go Wrong
The fastest mistakes usually come from three areas: misunderstanding odds, ignoring vig, and jumping into parlays too early. A bet can feel attractive because the payout looks big, but if the price is poor or the number moved against you, the ticket may be worse than it looks.
If you are starting from zero, I would learn moneyline, point spread, total, stake, bankroll, and implied probability first. After that, terms like hook, CLV, teaser, and same-game parlay will make much more sense when you see them on a live sportsbook screen.

Sports Betting Glossary FAQs for Beginners
What is the easiest sports bet for a beginner?
Moneyline is usually the easiest place to start because you are simply picking the outright winner. After that, most beginners move to point spreads and totals.
What does -110 mean in sports betting?
-110 means you need to risk $110 to win $100 in profit. It is a standard price on many spread and total markets because it includes the sportsbook’s vig.
What is the difference between stake, profit, and payout?
Your stake is the amount you risk, your profit is what you win on top of the stake, and your payout is the full amount returned on a winning bet. A $50 bet at +150 pays $125 total, made up of $75 profit plus the original $50 stake.
Why does the hook matter so much?
The hook often decides whether a bet wins, loses, or pushes. That matters even more in football, where margins such as 3 and 7 show up often.
What should a beginner learn before trying parlays or live betting?
Learn how odds work, how point spreads work, what vig is, and how much of your bankroll you risk on each bet. Those basics help you avoid the common mistakes that show up when betting gets faster or more complex.
