No jargon, no confusion — every term explained simply.
Action
When you have money riding on a game, you have "action" on it.
Bankroll
Your betting piggy bank. Only bet with money you can afford to lose.
Book / Sportsbook
The place where you make your bets - like DraftKings, FanDuel, or a casino.
Handle
How much money everyone bet combined. "The NFL Championship handle was $180 million."
Sharp
The betting experts - when they bet big, the lines move.
Square
Regular folks betting for fun, not professionals.
Ticket
Your betting slip. One ticket = one bet.
Unit
A way to measure bet sizes. If 1 unit = $10, "I bet 2 units" means $20.
VIGVig / Vigorish / Juice
The sportsbook's fee for taking your bet. That's how they make money!
Hook
That little half-point that can make or break your bet.
Getting Hooked
The worst feeling - losing because of that tiny half-point!
Key Numbers
In football, games often end with a 3 or 7 point difference (field goals and touchdowns).
Closing Line
The last odds before kickoff. Sharps try to beat this line.
Opening Line
The starting point - odds when they first come out, often days before the game.
Line Movement
The line "moved" from Chiefs -7 to Chiefs -7.5 because of betting action.
Dime Line
Low-juice moneylines. -150/+140 is a dime line (only 10 cents apart).
Nickel

Dime
"I bet a dime" means you wagered $1,000.
Push
Nobody wins, nobody loses. You get your money back.

"The Chiefs covered!" means they won by more than the spread.
ATS (Against The Spread)
How often a team covers the spread. "Chiefs are 8-4 ATS this season."
Pick'em / Pick
No favorite! Just pick the winner. Usually shown as PK or PICK.
Buying Points
Pay more to get a better number. Move Chiefs -7 to Chiefs -6 by paying extra vig.
Laying Points
When you bet on the team that's expected to win and must win by more than the spread.
Taking Points
Betting on the team getting the head start.
Middle
The dream! Bet one side at one number, bet the other side when the line moves, and win BOTH.
Hedge
Like insurance for your bet. Bet both sides to lock in some winnings.
Chalk
The team everyone expects to win.
Dog / Underdog
The team that's not expected to win. "I like the dog here."
Cinch
When someone thinks a bet can't lose. Warning: they can!
Fade
"I'm fading the public" = betting opposite of what most people bet.
Lock
When someone's super confident. "This is a lock!" Still can lose though.
Steam
When lots of money comes in fast. "There's steam on the Chiefs!"
Trap Game
When a good team might not take a bad team seriously and lose or not cover.

The most painful losses. You should have won but something crazy happened.
Sweating
That nervous feeling watching your bet play out!

What casual fans are betting. Sharps sometimes bet against the public.
RLM (Reverse Line Movement)

Handicapping
Doing your homework to figure out which bets are good.
Line Shopping
Like price comparing before buying. Different books have different odds!
Move Player
Someone who tries to predict when betting lines will change and bets right before they do. Some use computer programs to bet faster than humans can.
ROI (Return on Investment)
How much profit you make compared to how much you bet. 5% ROI is excellent!
Stale Line
When a sportsbook is slow to update their odds. Opportunity to get value!
Chasing
Betting more because you're losing. BAD IDEA! This is how bankrolls disappear.
Contrarian
Going opposite of what most people are betting. Sometimes smart!
Tout

The Cold Line

True Line
