WHAT THE H*** HAPPENED TO MY BFF?

My best friend wasn't always like this. She calls her -self stitches, and died her hair black, listens to some ppl called Black Veil Brides, Blood on the dance floor, Slipknot???? She has Bright *** Blue Highlights! Got her lip priced, and her nose. Wears clothes that are black and neon colors. She spends most of her time on myspace. Loves that band HiM and MCR. (eww) And her other friends call her emo! WTH is a emo?? and is she one!?! And she got bangs all over her right eye! (i'm using her email!!)
