A somewhat pejorative term used generally to refer to a woman's primary reproductive organs.

(Typically used by men uncomfortable and/or unfamiliar with the female anatomy, often for comic effect.)
Bro 1: I can't watch the game bro. My girlfriend has an appointment with her gynecologist today and I have to pick her up from the office.

Bro 2: Bummer dude. Is she OK? What's the problem?

Bro 1: Not sure man. All I know is that something's wrong up there in the gullyworks. I don't really want to think about it.
