A girl following a bastardized trend to rebel from the mainstream. Emo girls are usually 14-17, have little to no self esteem, shop at hot topic, listen to My Chemical Romance, or Green Day, or any other band that is inherently NOT emo in the true sense. They usually claim to be individuals, which is rather ironic because they look EXACTLY like their friends. Being Emo since 2004 is essentially conforming to portray ones self as a non conformist.
Emo chick: "OMG i love that new simple plan song! They look soooo emo now!"
Anyone over the age of 19: Emo died before you hit puberty, for Gods sake.
