A person who is obsessed (usually young females) with the "Twilight Saga" series of the film adaptations. Twinkies embrace all things Twilight with religious zeal, daily visiting fansites, quoting dialoge from the series, and stalking (online or in person) the films' stars, especially on the Vancouver BC movie set. Most Twinkies are "Team Edward"
Twinkie: "OMG!! Isn't Edward Cullen like so hot??? I'm gonna marry him!!!"
