A reference back to Revelation 17 where it talks about the great prostitute who was drunk with the blood of the saints. Only it's not biblical in reference at all. Used to describe an exceptionally evil woman who lacks any redeeming qualities, and generally makes your life hell. Example: She's a whore of Babylon. She's trying to take over my project and run it into the ground.
