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!

Over-Under Achiever

Someone who achieves the extra unecessary achievements, but does them in a half-ass fashion.

Patrick decided to be an Over-Under Achiever when he went the extra mile to do his extra credit, even though he already had a 103 percent in his english class. This project was done in a very UNorderly fashion. The rough draft write-up ended up having its title 'rough draft' erased and then replaced with 'Final Project'.

Over-Under

The act of getting a blowjob and your butthole fingered at the same time.

I questioned my sexuality, because I thoroughly enjoyed the over-under my girlfriend gave me. I filled her mouth up with my salt malt, and her finger smells like shit.
