When you squirt mustard (peanut butter works too) on your erect dick (flaccid works too) and come down on the fore head or cheek of your passed out brosky. Before, during, and after the event, you and your awake broskies must chant "Mustard DICK slap! Mustard DICK slap!" and record it with a phone or some shit like that.
Everybody: "Mustard DICK slap, Mustard DICK slap!"
(SLAP)
Everybody: "Mustard DICK slap!"
Victim: "What the FUCK!!!"
Everybody: "Mustard DICK slap, Mustard DICK slap..."
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).
