Smashman Sandwich

A maneuver that typically involves two guys in a fight in a bathroom, the larger individual will pick up the smaller, unknowingly walk backwards into the victim behind them, and smash the victim’s head into the bathroom wall with all of the force they possibly can exert.

mom: why do you look like you just got out of a fight?
