A group of people (mostly teenaged girls) who are obsessesed with the writer/actor Leigh Whannell from the movie 'Saw'. They are firmly planted in their beliefs that Leigh is the greatest person on the planet and must be protected from pesky non-obsessed people.
Girl One: Leigh Whannell is an idot
Girl Two (Leigh Mafia Member): FUCK YOU! HE IS THE FUCKING GREATEST!
