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.

"Bro, last night I finally talked my girlfriend into trying some butt sex, but damn if it wasn't a pump and dump, before I could even get off. Then she didn't wanna fuck the rest of the night cause she was so embarrassed."
"Dude! You never told me you were a turd burgler!"

"I met this frat boy online one night and he wanted me to come over and fuck him, but it was a total pump and dump. I asked him "bro u know how to be cleaned out right?" But I only pumped his butt for like two minutes before he said "Stop bro that's it i gotta crap!" Bitch looked so funny running to the bathroom I had to laugh, so then he wouldn't let me fuck him anymore."

pump and dump 

Assimilation of a lot of information and forgetting it as soon as the necessity for learning it is over. Originates from filling the fuel tanks of an aircraft, taking off, and then immediately dumping the fuel prior to landing in order to (1) train using the dump valve, (2) use up the squadron's allocation of fuel so that the allocation will not be reduced the next year (especially popular at the end of the fiscal year), and (3) ensure a safe landing (most aircraft cannot safely land full of fuel).

I will have to pump and dump for the engineering exam next week, since I have a multi-d final two days later.

We have to go through 500,000 pounds of fuel in the three days before October 1. It looks like we'll be flying nothing but pump and dumps.
