A psychological disorder falling under the larger diagnostic category of OCD whereas the sufferer, usually a contortionist, bends himself farforwardenough to repeatedly and compulsively sniff his own nuts.
Sadly, I found out that my cousin is being treated for his debilitating nutsniffing illness and part of the treatment is for the patient to have to tightly seal their nuts in plastic wrap day and night, so the pleasure reward is taken away and the behavior gets extinguished pretty quickly!
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).
