Can be related to any other teenie, for example a 'My Chemical Romance Teenie'.
Someone who has caught on to the craze of the 'Twilight' novel series by Stephanie Meyer and tries to catch up with the trend, but fails terribly. A Twilight Teenie will most likely read the first three chapters of 'Twilight', will not be bothered to read the rest and will find out what happens in 'Twilight' and the rest of the books by reading what it says on Wikipedia.
