pizza grease

Pizza grease is the various bodily fluids that accumulate in the folds and creases of the nether regions, eventually staining the bedsheets during and especially after sexual intercourse. See also quim or, as read in Achewood, "dunk oil."

I need to do a load of laundry; I don't know if I'm depressed or just lazy, but I've been sleeping in pizza grease for days.
