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!

Rod: So go on what was she like.
Tim: Rod, that old bitches snatch was the size of an empty pillow case.

a face when you cover up with a pillow case, when you're having sex, because the girl is ugly, but has a hot body.

pillow-case cum stains are the tell-tale ivory-colored remainders of cumgasms that a guy gets all over his wonder-pillow when he fucks it and blows his load.
When I was a teenager, my Mom asked me what the stains were on my pillow-case -- I didn't tell her they were pillow-case cum-stains -- I told her they must be slobber stains of mine made when I was asleep!

When your flatmate breaks in to everyone's room to leave shits in mysterious places, you then respond by taking a shitty pillow case and beating them with it. Thus a shitty pillow case

During an orgy, every one takes a shit in a pillow case and then proceeds to freeze the shit filled case in an ice box for 2 days until the shit grows brown crystals. Then every one proceeds to pass the pillow case around and eat the inside like its ice cream. Then when everyone's breath smells like shit, that's when everyone blows each other until everyone's scrotum turns pink from inflammation.
Person 1:Hey want to have another orgy?
Person 2:No! The Alaskan Pillow Case got me super sick. I have aids now. Thanks.
