As defined by an Ivy league scholar C.u.n.t is an acronym for = Can't Understand Normal Thinking!

An expletive you say when you just don't give a fuck about the consequences and you decide you are going make an irresponsible choice you might regret shortly thereafter. Similar to fuck it but more appropriate to use when your irresponsible choice may upset a stupid bitchy cunt that you unfortunately may have to answer to later.

The result of getting fucked and bred so relentlessly and violently by a big cock that makes a fags asshole become a sloppy cunt. Completely removing any last shred of masculinity they had left.

Someone who is a complete bellend

An insult OR a slang name for a part of a vagina.

Amongst other things can also be a derogatory term for a really hated person.

In Australia (maybe UK/NZ too - not sure), cunt can be used to address friends or to jovially comment about their slyness. Cunt is also becoming more commonly used by woman in Australia too, but it's still not a great word for the older generation.
