ex-popular
Teenagers who were popular in elementary and middle school but are nobody's in high school. These are usually people who developed earlier than everyone else and by mid-freshman year they were nothing. Most of the time this is a girl who every guy liked in middle school because she was hotter than everyone else but when other girls came out of their awkward stages she was forgotten.
