JJ: Hang on. Even I know that only happens in overblown and possibly illegal teen dramas.
A gathering of female characters, particularly teens or pre-teens. Often to talk about boys or make-overs. A staple of the simpler days of the Dom Com.
More often called a pyjama party in the UK (and, by adoption, usually in Japan as well), seeing as that's the general clothing worn at such an event. And anyway, who sleeps at one of these things? Wacky Fratboy Hijinx will often involve trying to gatecrash (or at the very least, watch).
Boys occasionally throw them as well, and they're full of tropes for tween boys. They just call them "sleepovers" instead of Slumber Party or Pajama Party, though - they usually consider these terms too associated to girls.
