Worse then a whore or slut. The cum dumpster drips the left over Sperm while looking for another ride. They don't care what they screw and you'll pay the consequences for it.
Have you heard? David is is hooking up with Amy? Hahaha he's screwed...that bitch is a toxic cum dumpster, his dickwill rot off in a week.
The person at you job that is totally useless. No matter what he or she does it accomplishes nothing. The pinnacle of uselessness, not specifically laziness, because very motivated or hard working people can be useless. Guzzling cum behind a dumpster will give their life more meaning.
