A guy who, during sex, can't contain his load for more than two measly thrusts. This leaves the woman shocked and extremely unsatisfied. Such men should either 1. Be shot 2. Kill themselves or 3. Become a priest. Such pathetic actions can evoke a very Angry Beaver.
My ex-boyfriend was a two-pump-chump, that's why he's my EX boyfriend.
I was so wasted last night that I was a two pump chump and passed the fuck out but now my girlfriend has an Angry Beaver.
