Someone who will have sex no matter how disgusting it is and it doesn't matter if the sex is with a boy or girl. In fact the douche pumper almost prefers sex to be nasty. They like having sex with girls on the rag and boys with full colons.
Oh my god Duane! did you really just make it with that stanky chick? What are you? Some kind of Douche Pumper?
