Zealous fans of the Twilight books and movies. They are usually female; hence the twat after the twi. However, a Twitwat can also be a man as once he becomes absorbed into the series or is dragged to watch the movies by his girlfriend or wife he ceases to be male for that period of time. Twitwats are also oblivious to Robert Pattinson's hatred for the movies, his character and how he is secretly laughing his ass off at them while getting rich and getting tons of hot bitches.
You're just a Twitwat who wants to be shagged by a sparkling vampire and a loser who turns into a werepoodle!

The Twitwats bleached their skin albino and wore yellow contacts to pay their respects to Edward Cullen.

The Twitwat imitated Kristen Stewart's excessive blinking in hopes of attracting a man like Edward Cullen.

A "TRUE" Vampire . Someone who bites their own arm when dinners ready. A Twi-Twat is a total twat who is obsessed with the religion of twilight.
