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!
