What do you call a group of Emos ? A suicide squad
I don't know what you are talking about, please explain.
In case you don't know what emos are, they are people who have a mental condition that prevents them from feeling happy or cheerful and they become suicidal over time.
Not all people who claim to be Emo's are chronically depressed or suicidal. If you do know anyone who experiences depression or anxiety, you should be sensitive to their situation and  educate them regarding suicide prevention.
