Half Pump Chump 

Defined as anyone who goes to the gym and does many reps and sets of a machine improperly. Often used to appear as if they have more strength than what they really do. Usually associated with buff guys or gym rats.

Bro, look at that dude squatting 415 over there, are his knees even bending?...what a half pump chump.

Half-Keg Pumpkin Fucker

An individual who fails, pathetically, to live up to a rather low set of expectations while either simultaneously or separately degrading themselves further by voluntarily engaging in far more outrageous and embarrassing behavior.

The Iota class finished only half of their keg while simultaneously engaging in sexual intercourse with a festive gourd. Bunch of Half-Keg Pumpkin Fuckers
