Against-the-spread: To bet against the spread is to make a wager that will be decided by adding points to one team or the other after the game is played. For instance if a team has a spread of “-7,” it has won against-the-spread if it is still winning after subtracting seven from its score.
Back door cover: Points that are unnecessary to the straight-up outcome of the game that are scored late in the game to cover the spread by a team that is very likely to lose.
Backed: A “backed” team is one on which the majority of bets have been placed. A team can be backed by the public in general or backed by “sharps” who are professional bettors.

Longshot: An extreme underdog.
Middle: To win both sides of the same betting proposition. Placing a wager on the favorite team at -2.5, then placing a wager on the dog at +3.5 after the line has moved. If the final score sees the favorite win by 3, the bettor wins both wagers placed and has hit the middle.
