Emo hair is hair that many 14-16 year old boys get to get girls. It is usually black and greasy,short at the back and it partially covers one or both eyes. Usually people get an emo haircut to look attractive, because there ugly as hell. I know many people who have an emo haircut and girls always flirt with him. But the truth is without their "emo haircut" their not that attractive.
Classmate: Are you emo?
Emo hair kid: Nah i just have this hair style so all the girls will dig me, im really ugly without it.
