(n.) when (either on purpose or accident) one poops on top of toilet paper in the toilet. The toilet paper hoists the poop above the surface of the water causing an exponentially greater stink. This technique is often used as a prank by not flushing the fecal matter minutes prior to leaving a friends residence.
Andy folded the toilet paper and placed it in the toilet prior to pooping with the sole intention of floating an assberg. He then left Kelly's apartment without flushing knowing full well that Kelly's new girlfriend would be over soon. The smell would not be beneficial to Kelly's game.
