Lately there's been a glut of wholesome, good-natured teens (see Jonas Brothers, High School Musical [1], and Vanessa Hudgens's snuggly ode to sneakers [2]). But this week's release of the 20th anniversary of the classic Heathers [3] reminded me that onscreen teenagers can be really mean. Actually, they can be downright vicious.

The girl group in Heathers was so mean they were essentially psychopathic. And then there's the famous pack of mean teens that torments Lindsay Lohan in Tina Fey's Mean Girls [4]. Rich girl Caroline Mulford in Sixteen Candles [5] is incredibly cruel (well, until she spends an evening with the geeky Farmer Ted). And of course, they're not always girls: Ryan Phillippe's character in Cruel Intentions [6] is about as scummy as it gets in terms of douchebag [7] teen guys.

Clear your mind of Disney stars and tell me about the most memorable nasty onscreen teens.
