Whats the exact meaning of these terms? (emo, prep, goth, scene, etc.)?

I'm not gonna take my time to read those senarios but all I'm gonna say is EMO KIDS DON'T CUT THEMSELVES!!! Kids that cut themselves are called cutters. Punks generally dress in a rebelous way and they don't give a **** about anything. Goth kids dress in dark clothing and usually have black hair and they are not depressed, they are actually very happy people with very deep thoughts that usually show when they write poetry.
