People who are so obsessed with twilight they begin to actually believe that vampires exist, or that they are one. A twicotic usually feels insignificant, and creates fantasies in which they are a vampire and are in some way the center of a twisting and self glorifying plot. It is basically delusions of granduer and magical thinking coupled with the not-so-subtle infulence of the culture spawned by the smash hit twilight. Symptoms may include claims about not having to eat regulalry, usually cryptically hinting at bieng impervious to hunger as long as they get blood. also look for avoidance of sunlight (not because of damage to the skin, but a psychological need to look as pale as the vampires in the movie), complaints of constant headaches usually accompanied by cryptic hints that they need blood. many other symptoms may occur.
