I dated a U.K. soldier who thought the word cun* was acceptable. I had to tell him otherwise.
The c-word in the UK and Ireland is used solely by men aggressively towards other men. It doesnt have any of the female ‘angle’ it does in the US. Men dont use it in anger towards women (we have other words lol) and women in the UK simply dont use.
Its a surprise to both British sexes that the US use is so completely different.
