guys at my school always talk about it.... is it like wresting or something?
Locker Boxing is a game played by primarily teenage hockey or lacrosse players in their dressing rooms or basements. These are generally not supervised by adults. Participants wear helmets and sometimes gloves and fight in the middle of a locker room. The object of the game is to score as many hits on the head as possible until the opponent is knocked down, gives up, or their helmet falls off.
Best sport ever. Put on a hockey helmet, gloves, and then punch your opponent in the head!
