Fan Casting Emo Teen in Sort by Tropes

Teenagers who are whiny, self-important, and generally trying to work their way to self-identification. The character type based off the Emo persona. The things that differentiate and identify Emo Teens are that they dress in black, listen to strange music (specifically, the "emo" genre, whence the term comes) and generally think that they are erudite (or, at least, surprisingly coherent). The slightly better-kept ones are usually political. If the character is female, she will tend to be extremely self-conscious about her appearance, but implausibly attractive all the same.
