A "religion" formed by teenage girls which may as well be scientology.
The religion is based on "Twilight" by Stephany Meyer, which is pretty much they're bible or, "Holy Book."

It's pretty much a bunch of girls obssessed with the main character Edward Cullen (hence CULLENism) who think Christianity is too mainstream...
Janit: What religion are you?
Kate: Cullenism.
Janit: *leaves*
