Ya know, labels wouldn't be bad, if it weren't for one main thing. Because everyone has different ideas on what 'emo' is, you can't really use it correctly. So, if I saw a boy with the black layered spikes and bangs, wearing a tight T with skinny jeans and whatnot, then I could say, "He's emo." As where I just meant to say, "He wears black and has that one hairstyle." But someone else might take it as, "He cuts himself and whines about life." So when I say that he's emo, different people will take it differently. So, there is no real correct definition. I don't think anyone could claim to be emo, because of that.
