Emo

Emo is defined in multiple ways. It isn't just some stupid music of genre, nor is it people who self harm. Emo is a character trait. It's a genre of music. However, some "normal people" listen to it and don't even know it. Emos aren't all mean, and the ones who are have a reason to be. Some are really nice, but like I said it's a character trait. It depends on the person.

This Emo song rocks.
Alina is a really nice emo, but she can be mean if you disrespect her.
