The co-worker that seems to try to sleep with any male coworker that gives her any type of attention regardless of any current relationship status. It is extremely obvious and nauseating to everyone but her, even other men. Can be shortened to "Princess D. Vag" or Princess Desperate Vag.
Oh, there goes Princess Desperate Vagina again. God. I keep doing having to do my work and her work, what a hooker.
