A woman with caked on make-up, usually found frequenting clubs and bars. When you take them home to bang them, you wake up in the morning with a ruined pillow-case from their massive amounts of make-up being rubbed off.
So after I banged that Pillow Case Ruiner last night I had to go out and buy some new pillow cases! Shit was nasty!
