What's the difference between goth and emo?
Emo: Hate themselves Goth: Hate the World
I don't know. But to me they both seem like the same concept - people trying to be different, by being the same as each other. But if I had to nitpick, I'd say that goth seems to be more about a theme, and emo is more about a feeling, if that makes any sense. It seems like goth kids like the same stuff, but emo kids don't necessarily like the same stuff (some like tats, some like torn up clothes, or whatever) but they all try to do things for the sake of pretentious and attention-seeking self-deprecation.
The difference is someone's opinion. No science involved.
