Used as expression of extreme exasperation. One is simply unable to express the sheer amount of exasperation any other way.

The pinnacle of rolling eyes at someone. Kind of like an extreme WTF.

Carries even more emphasis if in italics.
Person 1: "I honestly think Sylvester McCoy is the best Doctor Who ever!!!"

Person 2: "Fuck a cunt"

Person 1: "Guns N Roses is the heaviest band in the world. Ain't no one as heavy as them."

Person 2: "Fuck a cunt" (then goes and listens to Strapping Young Lad)

A group of cunts is called a fuck of cunts,

Almost like how a group of cows is a herd.

Get the Fuck of cunts mug.
Australian slang, short for 'shut the fuck up you cunt'. More or less the same as any Australian slang with the word 'cunt' in it, it's meant to be used casually or by some dumbcunt to sound threatening.

Stevo: FUCK UP CUNT! Git off ice, throw the first punch!

Get the fuck you cunt mug.
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"

Young bloke says "hooked up with a 10/10 on tinder last night, and she keeps msging wanting more(subtle/ happy voice)"Haha fuck off cunt"..
