Genital warts.
Fine if you are a male, because you can see them, but a
female with percy is very dangerous because her warts are hidden up in her wee
wee
First man: I hear that girl has a very bad
case of percy, and she gave warts to her new boyfriend. Now he has them all over his penis, and his tongue.
Second man: oh shit, it couldn't have been that good to risk that.
First man:
Dude, he couldn't see them. They were up inside her
stink.
