sprinkler starter

A VERY flamer gay! Taken from shortened "flamboyant" male homosexual (i.e. flamboyant, shortened to "flamer"). One who is SO gay, he could walk into a room, and because of his FLAMBOYant nature, he could set off the sprinklers.

Roger: Hey, Dave!! Did you know about Eloy? I found out he just came out of the closet!
Dave: Oh, come on, Roger! Eloy was SO gay, he could have set off the sprinklers when he entered the room. He just oozed of homosexuality. A complete flamer! A true sprinkler starter!
