In a way yes but no, you might be called a poser and will probably have to try to look mere emo to prove you're emo. Also emo isn't about self-harm or being depressed all the time. At first emo wasn't a culture, it was a type of music.
Depends on what you mean por "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 música genre, of course
