A young guy, shy, loner, usually a teenager, often a geek, who does not have a girlfriend and spends far too much time alone, often at home in his bedroom, when other people his age are out having a good time. The implication being that he is wanking or fucking, i.e. "Pumping" his mattress because he can't root a real Sheila. The meaning of the term and it's use might have nothing in common.
An underage drinker (under 18) is in a bar and bumps, into a grown man who shouts at him, "Piss off, you little mattress pumper".

Get the Mattress Pumpermug. An act performed usually by two female strippers, with an observer. The observer lays on the floor, then the first stripper lays face up on the observers chest so that his head is pretty much between her legs. The 2nd stripper then lays face down 69 style on top and proceeds to perform cunnilingus on the first stripper while the observer gets an up-close view.
