A person who brings hype and enthusiasm to a party, who helps break the ice so partygoers have a good time.
My university's student newspaper always had wanted ads for 'party pumpers' to work at bar/bat mitzvahs getting the kids dancing and enjoying themselves.

When you are trying to squeeze your fingers together but you can't. Mainly caused by excessive masturbation combined with cycling into work.
'God damn my hands are hurting, I can't squeeze my fingers together, my girlfriend (who is a physio) tells me it's "Pumper's Doom"...'

(Male Version of Swamp Donkey) a bro who pumps his meat then pumps on Drunk swamp donkey} girls at bars or boats. They have low IQs and love showing off their really shitty tattoos In the summer. They usually have some wealth, (not acquired) but definitely live in the suburbs. If they live in the city the meat pumpers flock to very touristy/douchey areas. In the winter you can detect a Meat Pumper by smell. (Drakkar Noir, Axe Body Spray, Old Spice products, etc)
Wow look at these meat pumpers...they look like they not only got their wardrobes from Sears in Greece...they also smell like they sampled everything at the fragrance counter as well! Pee yew!
