"Emo" is the name of an american cult. They absolutely hate their life and would rather kill themselves than let out their anger on a stress ball. Can you see the pattern of stupidity here?
Emos hate their rivals, Goths and would do anything to kill themselves to avoid them.
Emos often engage in sporting activities such as slitting their wrists and being anti-social, because emos don't care about their miserable lives.
