when you are in a bathroom stall, take a large amount of toilet paper or paper towels (anything 'dunkable'), dunk it in the pissy/shitty water, and throw at target.
Guy 1: timmy threw some wet paper towels at me while i was taking a dump, so i gave him a wet johnny right in the face!
Guy 2: it's the only proper revenge for being hit with a wet paper towel while pooping.
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).
