When a male engaged in vigorous anal sex breaks his dick inside said anus. Upon the breaking (and after all the anal pressure) the person receiving the anal sex becomes incapable of containing themselves and releases their fecal matter all over the broken penis. Therefore, making it a "Rusty Turn Boner."
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).
