A girl 17 or older who really likes hello kitty and seems cute and innocent, but turns out to be really freaky in bed. (in all good ways of course.)
Bro talk: man, I met this girl who really likes hello kitty man, and I thought she was gonna be pretty regular in bed but dude, I'm telling you. Total freak, and I love it. She's a hello kitty undercover freak!
