"What is it about good sex that makes you want to shit? Must be all that pumping... pump and dump... "
by Justinsideyou October 19, 2020

Another name used to describe the gluteus maximus, the derriere, the buttocks, the booty, the ass! Usually used to describe the buttocks of a well endowed woman/man (woman/man with a big booty)! Used most often by men who prefer the position "doggie style" or by those who really appreciate the lady's posterior attributes!
"Baby, those PUMP LUMPS are lookin good in those jeans!"
"Did you see how big that girls butt is? I'd like to get hold of those PUMP LUMPS!"
"OMG BECKY, did you see her PUMP LUMPS?"
"The bigger the lumps, the more he pumps!"
