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!"

The greatest feeling you can get in the gym, or the most satisfying feeling you can get in the gym, is, the pump.
Let's say you train your biceps, blood is rushing into your muscles, and that's what we call the pump.
Your muscles get a really tight feeling, like your skin is going to explode and it's really tight it's like someone's blowing air into your muscles it just blows up and it feels different. It feels fantastic.
It's ehh as satisfying to me as "Cumming" is, you know as ehh having sex with a woman and Cumming.
And so can you believe how much I am in heaven?
I'm like eh getting the feeling of Cumming in the gym, I'm getting the feeling of Cumming at home, I'm getting the feeling of Cumming, backstage when I pump up when I pose out in front 5000 people, I get the same feeling. So I'm Cumming day and night! I mean it's terrific, right? Ahaha, so you know I am in heaven!

the act of farting, or releasing built up stomach gasses through your anus. Pumping is sometimes used as a more savory term for the act because sensitive parents have an issue with the word 'fart', and deem 'pump' as less disgusting and more acceptable.
I really have to pump right now my my friends will smell it, and know that my pumps are stinky. I must hold my pump in

When a male is having sexual intercourse and just before the male is about to cum, a random nun comes out of the closet and pump fakes and scores, giving the male blue balls. OH FUCK.
"Mother Tamara has the best pump fake in the league... Blue balls everytime fucking up my game, bruh"
