When someone heterosexual describes something (usually a joke) that is or relates to homosexuality when in reality the person describing is not homosexual.
I can't believe Manuel & Caleb were making some Gaf ass jokes in front of their girlfriends at the party yesterday.

Get the Gafmug. Reverse of the word Fag because of censorship and with purpose of missleading sensitive individuals.
Man, YouTube will demonetize me if I say that as is. Gotta say it as GAF now so only subscribers know and it'll make me sound cool.

Get the GAFmug. In the Air Force in the 1960s we used GAF for Give a Fuck, but the joke was the Go Air Force posters we saw.
Also DILLIGAF was an extension that we used: "Do I Look Like I Give A Fuck?"

Shortened way of saying that you don't give a fuck. Instead of I don't give a fuck, you just say I don't GAF (pronounced gaff).
