Attention whores. Kids and young adults who really don't have any actual problems, and instead decide to use their creativity, or lack thereof, to craft false problems.
Emo kids are mostly seen with acoustic guitars and My Chemical Romance attire, as well as black hair that simply screams "kick me in the balls as hard as you can".
High-pitch nasally voice can often be heard uttering the words "You just don't understand", followed by the sound of slamming door, then muffled whimpering as the individual proceeds to scratch their wrist, hoping you'll take notice of their weak and futile efforts to portray suicide and/or self-mutilation.
But most notably, Emos keep records of thier so-called "problems" in diaries. These records mostly include pointless whiny rants:
"Dear Diary, those stupid jocks at school think I'm gay. Why can't they understand that heterosexual boys like me just like to kiss other heterosexual boys once in a while. They're so mean, and it depresses me... They say I'm Emo, even though I'm just misunderstood."
"They just don't understand"
"And Karen dumped me today. She says I'm the perfect guy, and that I'm always there for her, just like when her Chimichangas were too cold, and she ended up cutting her wrist out of shear depression. She says it's not me, it's her. She says I'm too good for her. I love her so much... I think I'll express my undying love for her by throwing my pillows and crying... and perhaps I'll write a love song and sing it off-key..."
