The noise a person might make when they are close to shitting themselves. Often made during the run-up to the toilet to signal to others they are desperate. It is like an extended "oh no", but very drawn-out to add drama and excitement to the situation. This noise may be heard throughout the shitting process, and will often be accompanied by vigerous sweating and closed eyes due to severe pain yet a sense of relief.
(Running to the toilet), ooomph! oooooomph! (People move out of the way). (Sitting on the toilet, with closed eyes). Ooomph! Ooomph! "Dude, can you hear that guy shitting? He must be desperate". Oooooooooooomph. (Leaves toilet).
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).
