pump and dump

Anal intercourse between two guys (usually frat boys) or a man and a woman (usually a frat boy and a drunk sorority girl) wherein the receiving party finds it necessary to hurriedly scuffle to the nearest bathroom to release a prodigious shit immediately following, or sometimes before, the butt-fucker ejaculates. The pump and dump results from a lack of preparadness: although the lower colon may seem vacant when probed with the finger, the impending turd is close enough to be stimulated by the thrusting action of the penis, which may or may not come into contact with said turd. In the event of a pump and dump, the pumper automatically becomes a literal turd burgler, having stimulated the release of a turd that otherwise would have emerged at a more opportune time. A more extreme version of the pump and dump, known as the anal sexplosion involves a high velocity expulsion of the mixture of lubricant, semen and liquid feces that accumulates in the colon during anal sex when the receiving partner isn't completely empty.
