A religion for people that don't know what to do with their lives. Which are all Twilight fangirls.

They obsess over Edward Cullen (Hence the word, CULLENism) Believe Stephanie Meyers is a god and that Twilight is the new bible. Often they scare people with their new found "religion" or if the person says they don't like Twilight, or think it's average, they'll beat that person into submission or call you a fat-ass with no life (Quite ironic, non?)
Person 1: I'm conducting a survey to see what religion people are, may I ask what yours is?

Person 2: OMG, I go by Cullenism!1!! You've never heard of it?! Edward Cullen's soooo hot!!!11 Stephanie Meyer is a god and Twilight is the new bible!1!! You should joi-

Person 1: *runs away*

Person: YOU FAT-ASS!!!11one YOU HAVE NO LIFE!!1! RETARD!!11oneone D:<
