The name given to fans of the country/pop singer/songwriter named Taylor Swift. They are the most amazing fans to her, supporting her through everything she does, and voting for her for award shows like the Teen Choice Awards. Most Swifties will stay Swifties forever. Well, at least I think they should. Taylor is lucky to have the best fans in the world.
See that girl over there in the Taylor Swift jumper? I bet she is a Swiftie. Anyway, she is lining up to buy Taylor's new fragrance "Wonderstruck". And I can see she is also buying the "Speak Now" album.

A kind of obsession and mental health problem. a Swiftie always believes their idol is the best and no one would ever top her. They drag everyone but when it comes to themselves they act as innocent.
