As a funny after thought, there used to be no emo kids, just "Emo" as an insult from Hardcore kids. Not to be confused with punk or hardcore.
There are two types of emo kids: Dark and Bright
Dark emo kids often have really dark clothing, really dark eyes, and don't talk a lot. They are truly anti-social, might be quite content not having friends, and are truly introverted. Don't try to befriend them, you'll fail miserably.
Bright emo kids are the most poseur kids ever. Generally, they have great lives in giant suburban homes and are incredibly social, but use the emo movement as a ruse to get attention. They love to complain about every little thing that's wrong with them, and if you try to socialize with them and you're not another bright emo kid, you will instantly be inundated with bullshit. Generally, they tend to be of the more popular kind, and are the females of this type can grow to be quite annoying, and the men can grow to be quite frustrating as you try to convince them that their lives don't suck.
Bright emo kid: *cry* will you listen to my poem? I wrote it last night after my dad beat me. *cry*
Me: No. Can I see your arm? *rubs off ink* your dad didn't beat you.
Bright emo kid (in frustration): Ow, that hurt! That's a bruise! *cry*
Me: No it isn't. I just wiped it off. *Makes angry faic* Don't lie to me man.
ANNOYING EMO KID: those kids who regularly max out daddy's credit card at hot topic and tell everyone how depressed they are and that they cut their arms up every night wanting to die (ok...where are the scars?). they only listen to 'underground' bands adn immediately stop when someone they think is popular or preppy starts to listen to them, or they see them on mtv (which they claim never to watch, but they still do). they intentionally do stupid and rebellious things trying to make authority figures mad, thinking it's cool. these people are attention-craving, tasteless, abnoxious emo kids. anything popular is completely disregarded to them. they also tell ppl that they think drugs are sooooooooooo cool, but are scared to do them, but do them anyway because they think it'll make them cool
ANNOYING EMO KID: the guy who draws on a bruise to make ppl think his dad hits him and who only talks to other ANNOYING EMO KIDS
What is the point of my life?
I hate everything.
TRUE EMO KID was most likely emo before this was a stupid fad. May shop at hot topic, but only if they actually like the clothing, not because they think it will make them look cool. Probably classified by friends and others as "emo"...the label is often not self-professed in the case of the true emo kid. Doesn't give a shit whether music is mainstream or not...it just has to be artistic.
2) The style of clothing stereotypically worn by fans of emo music. This consists of, in general: tight band t-shirts or vintage 80's t-shirts, longer (messy) hair often died black, tight (usual girl's) pants, shoes by Vans or Converse, messenger bags, anything checkered (usually black-and-white or black-and-pink), studded belts, thick-framed glasses, neckties, etc.
(Note: girl emo kids often cut their hair short in the back and angled down in the front, less often died black)
3) The mood that stereotypically displays being an emo kid. They are generally considered the subculture of high-school, and while sometimes referred to as manic depressive or "cutters," are usually quite social. Very romantic, often downtrodden. More realistically, teenagers who listen to heavy music and have no qualms with displaying their emotions. (ie, don't feel the need to prove themselves as "bad-@$$," like many rock fans.)
