1. A technique used by defenders to put attacking players in an offside position, by moving quickly away from their own goal to leave attackers offside.

2. A lady's 'backdoor' or 'back passage'.
That bag of chips I bought her was a good investment last night, not only did I get my end away, but I also managed to slip one in her 'offside trap'.

n. Defensive technique in soccer wherein the defenders closest to their own goal line all move simultaneously toward their opponents goal line just before an opponent boots the ball downfield. The object is to deliberately place any possible recipients of the pass in an offside position, and to allow soccer enthusiasts, who love to have their enjoyment interrupted by questions, the opportunity to again attempt to educate hockey fans on the nuances of the beautiful game.

Offside trap. Again. Look, get me some crayons and I’ll try to explain it in simpler terms.
