Someone (usually a girl, but
may be a boy), who is both a nerd, and a sket.
They try to be
popular by dating loads of guys and having sex with anyone who has a dick, not caring who it is and just thinking them as "walking sex", but at the end of the day they're just nerds trying to act cool.
They may be intelligent, nice-looking girls, but they'd do anything to be
popular. Sort of strange suck-ups!
