A term usually used in video games. The act of jumping on top of someone or something to kill/destroy it. Much like jumping on Goomba's in the Mario games.
Player1: Dude, I totally Goomba-stomped the guy at the bottom of the elevator shaft.

A masochistic sex act that involves a man laying down and his sexual partner jumping up and stomping on his crotch with both feet like Mario stomping on a goomba.
