Over-Under Thunder 

When a girl farts and queefs simultaneously, placing one hand "over" her vagina, and the other hand "under" her legs, on her ass, both in a cup-like position. When said girl farts and queefs, she moves her cupped hands from a closed to open position, thus creating a loud "Over-Under Thunder." This act is common when girls have pajama parties.

Cindy: Uh-oh! I have to fart and queef at the same time! What should I do?
Stacey: You should cut an Over-Under Thunder!

Prime: 'I don't know, what DO you call Negative One, alone, in a room?'
Moss: 'OVERNUMEROUSNESS!' :P

Judge: 'Yes, that is a word, and the joke does make sense ;)'

overunderrated

Something that is underrated, but not nearly as great as those claiming so would have you to believe

Shadow of the Colossus is an overunderrated video game; people love it, but it's boring and looks like crap.
