When someone eats some sort of string such that when one takes a dump the shit is formed on the thread of string, and when exiting the anus performs a bungee jump-like action in the toilet bowl.
Hey dude I was watching the fishes in the aquarium and i ate a string and my shit was totally bungee dumping!
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
