Carrying on in a gay and/or homosexual manner in public...usually involving two completely heterosexual male friends.

The definition of Faking off means when two male or female people hook up and get caught doing it

oh, that's just lovely. You put words into my mouth about doing such a sickening activity as that. I guess you think you're better than me because of it, don't you.

Carrying on ridiculously unloyal..

When two male's either homosexual or sometimes not engage in sexual intercourse or foreplay.
Fagging off can also be used to create a sense of discomfort around non gay men!

Has nothing to do with fuck off ! It's used instead of "stop being a fag!"

When two fags are vying for ultimate fag supremacy amongst their fag peers.
