Usually a girl, the stereotypical Plastic originates from the US of A. Their parents are usually rich, they have to flirt with their daddy and act like a daddys girl to get what they want from their dad, and they are the envy of most girls at their school. They're known to be bitchy, backstabbing, flirtatious (only with the Jocks), and just down-right mean. Their parents are rich enough to afford to buy them REAL designer labels such as Gucci, D&G, and Prada. They think they're better than anyone, and look down on anyone who isn't like them, i.e grungers, goths, nerds, and the poor. Watch the movie "Mean Girls" to get more insight on these horrible girls.
Plastic: Daddy, I need £300 for a new Gucci hangbag

Daddy: But sweety, I don't have enough money this week.

Plastic: BUT DADDY, I WANT IT! {Looks at Daddy in a flirtatious way}

Daddy: Oh okay...

A group of "students" in a school that doesn't do much but roam the halls during class , bitch and moan about retarded Facebook or Twitter happenings, get offended when someone tells them to shut up when the teacher is trying to get the word out and Basically, make everybody else life in high school a living hell.
They think they dress awesome, look awesome and is the epitome of awesome and EVERYBODY loves them, but in reality THEY SUCK, THEY WILL NEVER MAKE IT IN LIFE AND THEY SHOULD JUST JUMP OUT A WINDOW WHILE THEY'RE STILL AHEAD.
The girls will end up being their dad's or "husband's"sperm dumpster and the guys will either end up dead or in jail being some big hulking guy's "Midnight Snack"
Example:
Boy: Aw fuck here comes a plastic girl, have you heard? she sucked some plastic guy's dick in the bathroom.
Girl: Yeah, she's a slut but people still hang out with her.
Boy: Well duh! They're only there for the benefits!
Girl: What's the benefit? Herpes?
Boy: Fuck, I don't know and I don't want to know
Girl: I'm tired of plastics, I wish they would just die!
Boy: The feeling is mutual.
