A genuinely sweet, or pleasantly odorless expression of flatulence. Though not always a fart cut by homosexuals, they do tend to do this while they bake cookies and share a laugh about it.
"Pete did you just fart? It smells like freshly cut grass, what have you been eating, sperm?"
"Sorry bro, that was a Gay Fart"
"A Gay Fart?"
"Let's take our shirts off and kiss"
