My younger son kept calling his friends "emo" so I had to ask what it meant.He says it means an emotional person.According the the Urban Slang dictionary it means:Genre of softcore punk music that integrates unenthusiastic melodramatic 17 year olds who dont smile, high pitched overwrought lyrics and inaudible guitar rifts with tight wool sweaters, tighter jeans, itchy scarfs (even in the summer), ripped chucks with favorite bands signature, black square rimmed glasses, and ebony greasy unwashed hair that is required to cover at least 3/5 ths of the face at an angle.http://www.urbandictionary.com/define.php?term=emo... whatever
Emo around these parts is someone who cuts themselves for attention.
In London if something is cool and you really like it you say:"That's SICK man!"Don't ask me why!
