A bunch of high school girls who think they are awesome and everybody likes them. They think people call them plastic because they are beautiful and people love them but oftentimes it is just because they are wellknown fakes. Usually made up of fake blondes but may have one or two less popular exceptions.

This term was coined globally with the release of the movie "Mean Girls", which has become almost guidelines for how the "popular people" or "totally cool" groups act.
Girl: Man, I wish I could be one of the Plastics.
Otherone: Why, they are just losers who think they're better than everybody else.
Plastic: But I thought everybody likes us, we're just so awesome!
Girl: Oh ok, you're right.
