Emo is not one thing, it is actually multiple things, and either can make you Emo;
Emo is a style, wearing
dark clothes usually black, black painted nails/hair, and the hair can be shaggy and swooped across the
face usually
long. Emo can also be a mentality, someone who is in
tune with their own emotions, they understand themselves, self harm too but we dont talk about that. One more thing that could make you emo is music taste, for instance, all types of rock and metal genres fit into emo. Some artists that would fit the emo genre would be:
Joel Faviere, Get
Scared, Black Veil Brides, and so on.
You dont need to fit all the criteria to be Emo, just one is fine, And if you fit some of it and dont want to be called Emo, then thats alright, you do you.
