Similar to the word bullshit but in a sulkier content. It's something that sucks horrible. Bullshit is used as foul diction for something that is a bunch of nonsense and therefore you can relate bullsuck as its "sister" word, but not as profound. This word takes a lot of pressure built up from that disappointing moment and allows you to not feel guilty about your language, enabling you to achieve a sense of relief making you feel better in the end, so it's a win-win situation.

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)
