Juice - interest charged to bet; example: 10% juice to bet the OVER means you bet $110 to win $100 OR bet $100 to win $90. You only pay juice when you lose; default juice for most straight bets is 10%
Liveline - betting during the game; spread, over/under adjusts during the game
Moneyline - pick whichever team wins, with no point spread. Moneyline odds change based on how strong one team is versus another
Nick line, Nickel line - line/account that charges 5% juice instead of the standard 10%
Over - betting that the total will be over the set spread/line; can apply to a quarter, half, game, team, player totals
Parlay - combine 2 or more single bets to increase payout; push reduces/removes it from counting (example: 2 team parlay turns into straight bet). All bets in parlay have to hit for parlay to survive; if any bet in a parlay fails, parlay is dead. No juice is charged for parlays
Push - tie, no winner
Sharp - experienced, veteran gambler
Spread - how much one team is favored over another, or how many points one team is getting from the favorite (usually before quarter, game, half starts)
Under - betting that the total will be under the set spread/line; can apply to a quarter, half, game, team, player totals
