Girls that are apart of the Facebook group called "Boston Directioners" These girls are literally legends, they've gotten shout outs from; Lily Halpern, One Direction US and even Liam Payne from One Direction. If you're a fittie you're one of the most attractive people that has ever existed. If the boys of One Direction met you they would go into cardiac arrest. Everyone wants to either be a fittie or know one. Fitties dominate the world of One Direction. They consider each other sisters rather than just directioners. Every fittie has a best friend. #fitties4lyfe
