A girl 17 or older who reallylikes 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 hellokitty 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 hellokitty undercover freak!
