In a way yes but no, Ты might be called a poser and will probably have to try to look mere Эмо to prove you're emo. Also Эмо isn't about self-harm или being depressed all the time. At first Эмо wasn't a culture, it was a type of music.
Depends on what Ты mean by "emo." It originated as an insult to overemothional people, but then evolved into a style of music. So if ur talking about the insult, yes. If you're referring to the Музыка genre, of course
