Normally a 15-17 year old teenager. Considers themselves to be much more in touch with their emotions than anyone else; whereas they really just feel sorry for themselves. Most emo's will claim to be depressed, or simply misunderstood. They think they are unique, and fail to realise that they actually look like half the teenage population of south england. You can recognise an emo by looking for these general characteristics:
SKINNY JEANS (both boys and girls) The tighter the better. If an emo can hardly walk because of their jeans, then they've reached optimum emo status.
STRIPEY JUMPERS. Normally black and grey. If you're a boy, this should again be worn as tightly as possible. Breathing comfortably is a luxury you may have to sacrifice.
TATTY CONVERSE. Usually drawn on, as most emo's regard themselves as artists.
BLACK LONG HAIR COVERING ONE SIDE OF YOUR FACE. Vision can be compromsised for style as an emo. Try and make it as greasy as possible.
Finally, emo's MUST look down on everyone else, accuse them of being uncreative, judgemental, and the sole cause of their 'depression'. If you're a hardcore emo you'll cut yourself occasionally. If you're not, then you at least have to pretend you do.
