Someone who epitomises the sappy and gay elements of regular demographics such as goths, teen boppers, punkers, skaters, surfers, etc.
Emo fag: My girlfriend, Janie, blocked me on Yahoo!IM. I knew she blocked me 'coz she was on AIM, but she didn't know I knew that. This makes me sad like the time my Taking Back Sunday signed skateboard was run over. I think I might take some Sudafed to help me bring and end to this life.
