GFB

GFB is short for Gay Fucker Boy. It’s a term for a guy who likes to fuck other gay boys. It doesn’t necessarily mean that a GFB is also gay but he could also be a bi, but he likes to fuck other gay dudes.

Yo, Tom texts me last night and ask me about my day. Is he gay or something?

Aw, man! Don’t you know? He’s totally a GFB. Tell him you’re not gay and he’ll back off. He only fucks gay dudes.
