Dumb Dirty 

A person who lacks intelligence and common sense and is outrageously promiscuous.

"How does that girl not realize that that guy doesn't want to hook up with her...and that three of her friends have already slept with him?! What a dumb dirty."

"I can't even stand that bitch. She's such a dumb dirty."
