A word used by prejudiced no-hopers, to make themself feel better about their shallow labelling. Often used to describe music taste, fashion taste, depression, hair cuts, art and, wierdly enough, colours.
'Emo' is a music genre, yet it is used in the wrong context and usually mistaken for a style label for a teen gothcult. Its a bit odd to think you are an 'emo', so try a different style. Don't try scene unless you would be commited to it. Don't a poser.
