Its a trend currently circulating of teenagers aged 13-18 who are obsessed with self-pity, labelling themselves "Emo Kids"
they love to listen to hard punk about being rejected by girls, suicide & self harm.
Appearence consists of jet black (or pyroxide blonde) hair with a large lopsided fringe usually covering a single eye, VERY tight clothing, especially the jeans.
Fav bands are My Chemical Romance, the used, finch, Aiden, Panic! at the Disco & Fallout boy.
basically its a trend based on being an outcast to society...... even though they're by far the majority (Ironic huh) XD
