Piss-Cum Strat

Piss-Cum Strat, although abnormally named, is a glitch in the browser game Chirpy Reverie in which Chirpy, the main character, gets clipped into a wall and his "Grounded" flag for a few frames, allowing him to perform a secondary jump.

Bart performs a Piss-Cum Strat in the final level of the game to save a dash.
