1. One who is so gay that his gayness dwarfs the gayness of all other fags. (Fag Juggernaut)
2. A fag of astronomical proportions.
3. A really big bundle of sticks.
A term combining fag and astronaut, stemming from the use of fag as a pejorative. Essentially the same meaning as fag, but with amplified meaning. Literally means a gay person, but as with the word fag itself, is often used to describe loser, idiot, pansy, or any number of generic insults.
