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
