These mythical worm like creatures are said to live off bacteria that forms in old bottles of douche. Upon use they can travel into the woman's vagina and take up residence, much like an STD.
Jason: Hey Sally; have you ever consider checking your vagina for douche worms?
Sally: Douche worms, in my vagina?
Jason: Yeah, it's more likely than you think!
Sally: They're in me. I can feel it... I used an old bottle of douche last week, and I have been wondering where that tingling sensation has been coming from.
Person 1: You just locked me out of the house!
Person 2: Haha, I know!
Person 1: I'm gonna have to kick you in the penis because you're a doucheformer.
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).
