To plug your pooper in any way possible when a toilet is nowhere to be found, or in order to keep from shitting your pants in public. Mostly done by clenching with the buttocks and, in the event of a prairie dog, sitting on the heel of your foot in an attempt to shove it back up your bum.
Albert: "Man I really gotta poo."
Mick: "Scunch it, man. Scunch it like you mean it."
Albert:"I don't know if I can scunch it until we find a rest stop."
Mick: "Then sit on your heel."
Albert: "Thanks bro."
