A grade A+++ Internet troll who is mostly likely female and acts like either a grammar nazi or some kind of extremist, usually targets people who are autistic, furries or bronies/pegasisters. Is on several occassions extremely hypocritical, as in - you can't make fun of her but she can make fun of you whenever she wants.
Mostly found on sites like the Encyclopedia Dramatica forums and targetting anyone on the acceptable targets list including the afformentioned, is mostly a hateful female most likely on her period or suffering from PMS if they're an adult, or just acting all bratty and superior to everyone else if they are a teenager.
Can be also seen lurking on youtube posting the numerous 'Just Kill yourself' comments.
"I talked to Jen on facebook and she told me to kill myself."
"Don't listen to her, she's a Grand High Bitch"
