KOAF is an acronym meaning: king of all fags
Dude, Joseph Oh is such a KOAF, look at him touching Harrison and Stephen inapproprately.
King Of All Farts, an exceptionally long, noisy, and smelly fart, for example a fart from eating extremely garlicky food. Pronounced "KOH-aff".
Man, any more of that KOAF and I think this house will fall apart! What a stiiiiink!
