Beggar's Canyon
A deep and penetrating insertion of spandex into the buttocks, often seen during professional football games. Named after the desolate geographic formation referred to by Luke Skywalker in Star Wars: A New Hope.
Guy 1: Dude did you see the Beggar's Canyon on Rocky Bernard at last night's game?

Guy 2: Yeah man you coulda fit two T-16 Skyhoppers and a squad of podracers through that thing.
