verb - to conceal one's feet in a paper bag while giving oral sex in a public place, thus creating the illusion that only one person is present. Common in rest stops and fitting rooms.
Refers to hiding a girl's face when she has a hideous face but a banging body. Similar to butterface.
Corey - Hey, check out the fat juicy ass on that chick! Is that Alyssa Mckay?
Rick - She sure does have a lewd ass! Wanna gangbang her?
Corey - Nah, her face is nasty! Where will we find a paperbag to cover the butterface?
Much like a butterface. A girl who has a great body, but a rather unattractive face. She'd be great in bed, but you just have to cut holes out of a paperbag and pop it right over her head.
GUY 1: "Hey look at that Nancy girl. Nice ass"
GUY 2: "Yeah, but look at her face."
GUY 1: "She's a real paperbag princess alright."
GUY 2: "Nice one."
