Australian term mainly used to disagree. Different tones can denote different meanings to the term i.e... Angry tone- "Fuck off Cunt" translates to- Please remove yourself from my direct area and deafen me with your silence before confrontation escalates.....
Subtle or even happy voice, Example... Someone tells an untruthful story, the response "haha Fuck off Cunt" Translates to- I find your factless story somewhat humorous although I know its untrue, But I hold you in such high regard I give you the honour of referring to you as Cunt. In Australia, when you call someone a cunt they're your mate...Call someone mate they're a cunt.
Out late at Pub and blind. Someone starts talking shit to your Mrs and goes to far, refuses to go away amicably so harsher directions required (angry voice) "FUCK OFF CUNT"
