A person, usually a hopeless teenage girl, who stalks emo guys, despite the fact they're gay or have a girlfriend.
They normally are dressed in black, wear band shirts, put on shitty makeup, and carry around Hello Kitty cameras to capture their loved ones eternally. They might take take to take a few closeups of themselves so they can add it to their myspace while they're at it.
Emo Stalker: 'OMG! He's so cute! Awwww...I want to go out with that emo boy!'
Normal Person: "He has a girlfriend."
Emo Stalker: 'Why does everyone hate me?!' *runs off to take pictures of her emo crush*
