A loud inconsiderate harley driver and/or owner, often making noise to add on to the sound of the bike with his or her mouth. (A person who is interested in one day purchasing a Harley is called bikecurious). See faggot and bikecurious
If he is a homosexual but does not ride a Harley he is not a fag.
If he is young and is thinking of riding a Harley he is bi-curious.
That fag over there is making a lot of noise.
