Many are prone to being a prep. Others, a very little emo this happens toward more later in 13 age most only like the music. Most likely green day obbsessed (like mui).

A girl who thinks she is old enough to do whatever she wants, sometimes going through the "scene" phases. She tries to fit in with older people usually. Most of the time this person looks older than 13 or tries to act older than 13, she usually dates people older than her. She tries to be adventurous and tries new and dangerous things.
