Flitty Cross Dresser Gay Phonie
Most famous usage from The Catcher in the Rye by J.D. Salinger in which the main character, Holden Caulfield, refers to men with long hair, female features, the wearing of female clothes, or just overall phonies in the area of gender. They also, according to Holden, say "Try this for size","goose the hell out of you while you were going down the corrider", and leave bathroom doors open.
"The other end of the bar was full of flits. They weren't too flitty-looking-I mean they didn't have their hair too long or anything-but you could tell they were flits anyways." The Catcher in the Rye
"He was always telling us about a lot of creepy guys that go having affairs with sheep... And flits and Lesbians...all you had to do was mention somebody-anybody-and old Luce'd tell you if he was a flit or not." The Catcher in the Rye
"Look at that chick down there, with the stubble and boob job. Such a flit."
"Stop being such a flit John. No one cares about you meeting Liza Minnelli."
