queeb

The loud fart sound made when the seal is temporarily broken while sucking on a penis.

Brother: Knock Knock!
Other brother: What?!?!
Brother: What are you two doing in there?
Other brother: Nothing!
Brother: Bullshit! You're fooling around - I just heard a queeb!

mouth fart

The sudden expulsion of air that shoots through your closed lips when someone says something really funny or really stupid.

Bimbo: I think I'll run for president
Normal Person: Pfbtpfbtpfbt!!! You just made my mouth fart.

bi-vomit

Vomit that goes both ways. When you puke a little in your mouth but swallow it before it escapes.

Dude! Your fart smells so bad that it gave me bi-vomit!
