Wiki's explanation of Emo is basically regarding music and fashion and not so much about the person. Emo's are very emotional and sensitive. Very woe is me, the world is terrible, my life is terrible, everything sucks, everybody hates me, nobody likes me, I'm gonna eats some worms. Along with that type of mindset there is some cutting and self hatred type acts involved. They are very narcissistic, usually of junior high age and I can't stand them.

An entire subculture of people (usually angsty teens) with a fake personality. The concept of Emo is actually a vicious cycle that never ends, to the utter failing of humanity, and it goes something like this:
1. Girls say they like "sensitive guys" (lie)
2. Guy finds out, so he listens to faggy emo music and dresses like a dork so chicks will see that he is sensitive and not afraid to express himself (lie). He dyes his hair black, wraps himself in a stupid looking scarf, develops an eating disorder, and rants about how "nobody understands".
3. Now an emo guy, he meets Emo chick and they start dating, talking about how their well-off suburban lifestyles are terrible and depressing (lie)
4. Emo guy is just too much of a pussy. His penis is too small, he's too depressed to bathe, and has more mood swings than emo chick, and he doesn't even have a menstrual cycle. Emo chick dumps him, saying "It's not you, it's me." (lie) as she drives off with Wayne, the school jock and captain of the football team.
5. Emo guy goes home and cries, proceeds to write a weak song and strum a single string on his acoustic guitar. Another emo chick sees how he is so in touch with his feelings, and the cycle continues.
This is the sad truth of the emo lifestyle/music, and now that I look at how pathetic it really is, maybe the emos DO have something to cry about!
When she sees how sensitive and emo I have become, she'll definately go out with me!

Like a Goth, only much less dark and much more Harry Potter.
My life sucks, I want to cry.

A group of white, mostly middle-class well-off kids who find imperfections in there life and create a ridiculous, depressing melodrama around each one. They often take anti-depressants, even though the majority don't need them. They need to wake up and deal with life like everyone else instead of wallowing in their imaginary quagmire of torment.
