1) The fans of emo
music (emocore, emotional hardcore), a music genre consisting of hardcore rock with angsty lyrics and a good dose of screaming. The singers/screamers of emo
music are typically relatively young guys with feminine voices. Emo bands are also (in stereotype) primarily from New Jersey.
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.)
Emo
kids listen to many of the following bands:
Thursday, Death Cab for Cutie, UnderOath, Fallout Boy, Taking Back Sunday, My Chemical Romance, As Cities Burn, etc.
