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!
