An extremely over the top, overtly feminine gay man or teenage boy. Thought originally to be a reference to the Christmas Carol "Deck the Halls" which contains the line: "Don we now our gay apparel." It also conjures up images of a very festive (gay in the old sense) holiday. Someone who is Gay As Christmas is one of those homosexuals who are always "on" never sad and tend to prance about, seemingly defying gravity as they flit from one male party guest to the next.
Zach Efron had been called many things, especially homo, fag, flamer, screamer, sausage smoker and just plain queer but after seeing him flit from boy to boy at the party last night, everyone agreed the best way to describe him is "He's Gay As Christmas!"
