well it depends if they were tight pants n black shirts all the time n they have cut marks on their arms n they have black or red or black n red hair then yea they are emo
Some boys who wear tight pants could be emo.. i guess. But the majority arent. You cant tell whether somebody is emo or not by their pants!!! The only way you could actually know is if they have more than one scar on their arm ( if there is only one they could have just fallen or something).

Idiots emo is a type of music and you don’t have to cut yourself to be emo!!!!!
