Over Under is a bathroom stall challenge where you must enter a public restroom and piss a clean stream over the divider to the neighboring stall, then lay down on the floor and bend your piss stream, under the divider, into the same neighboring stall. Over Under has recently been taken up by the speedrunning community. 100% runs of Over Under start when the stall door is locked and are disqualified if as little as a drop of piss hits the divider wall (This is known as Walling Out). If one Walls Out they still must complete the run by laying down in a puddle of their own piss and completing the Under portion of the run. If a speedrunner successfully avoids Walling Out their time ends when the stall door opens. Video evidence must be submitted to the forums with any Over Under speedrun

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!

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'.

Steve: Cool.

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.
