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.

Get it Pumped!

Instigate sexual relations forthwith, occasionally shortened to GIP. Originally started by proud fenians on the thehuddleboard.com, not by the smelly lot although they were certainly the first to use it in conjunction with members of their immediate family.

HB1: Ma missus has just farted out her snooze!
HB2: Get it pumped!

----------------------------------------

Chump pump

A person that manually bails a household sump after the electricity fails and they do not have a generator.

Dave and Sue spent all Saturday night working the chump pump because a tree took out their power lines.
