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!
When a car battery doesn't have enough juice to turn over the engine, but has enough to make the starter produce a very loud fast clicking noise, which is very close to the sound made by many sub machine guns.
Will usually scare the living shit out of anyone standing near your car.
Dude 1: That guy had a machine gun starter. It scared the fuck out off me!
