A rapidly growing altertanitive teen subculture, spawning from both hardcore and emo. They tend to care way more about the fashion then the actual music, ussually always re-dying thier enormous chunk of combed over hair, or cutting off the tips of gloves and taking pictures of them obssessively for online personals,(ie myspace, xanga, LJ). Many are rich suburban kids, newly introduced into the rock scene, and tend to add thier own teenie bopper style.
Many try to hug the style of straight edgers, despite thier lack of knowledge of what it is. Online they tend to add X's in everything they type or write. Thier ussually very femine, and highly into fashion.
