A Cum Dumpster is a woman or group of that only serve society by playing a key role of removing cum from the environment. This can be done by anal, vaginal, oral, ear, belly button, hand (as long as hand is then licked afterwards) intercourse. This does not apply to gays because gays do not exist, they are a government conspiracy. See Jenna Jameson.

Any girl who takes loads of semen up her snatch, down the hatch, in her crack, and on her back. These chicks are down with the creampie be it anal or vaginal.
I have the crabs now because Alice is a promiscuous cum dumpster and I had sex with her.

Any slackjawed gapemouthed semen hungry fuck socket that sucks on the snotty end of a piss-pole more often than is considered proper for polite society.
Janie is such a cumdumpster that i fully expect to find her faced down in an alley with nut stains on her back and joy juice dripping from every orifice.
