Prickly Pussy Face (PPS) is the face that you get the morning after you fall asleep on a prickly pussy (early stages of freshly shaved pubic hair, growing back in a spikey form). Sort of like the creases that you get after falling asleep on a couch.
Jen forgot to shave before her date with her new fling. Luckily she got drunk enough to have sex and forgot about her prickly puss. Her date however, did notice when he got rug burn on his face and crotch.
