There are certain words that simply sound different coming out of a British person's mouth than they do coming out of ours. Cunt, for example, is almost charming when declaimed with a lilting accent from the British isles. When I say it, with my hints of the New York City gutter hanging about the glottis, it sounds threatening and mean. And so the British use cunt much more often than we do, and nobody really gets offended.

Cunt - Wikipedia
Reflecting different national usages , cunt is described as a "usually disparaging and obscene" term for a woman  or an "offensive way to refer to a woman" in the United States  by the Merriam-Webster dictionary, but "an unpleasant or stupid person" in the Compact Oxford English Dictionary , and "a contemptible person"  in the Macquarie Dictionary of Australian English. In Australia and New Zealand, it can also be used as a neutral or, when used with a positive qualifier e. The earliest known use of the word, according to the Oxford English Dictionary , was as part of a placename of a London street, Gropecunt Lane , c. Use of the word as a term of abuse is relatively recent, dating from the late nineteenth century.
C is for Cunt
Pushed underground, banished from conventional language, cunt has long since been appropriated by patriarchs and misogynists and used as an utterance that disgusts or insults in the worst possible way. But cunt has not always been the most taboo word around. It was originally a term used to revere the wisdom of women, in particular the wisdom of her genitals. In pre-agrarian days, cunts were tacitly celebrated as purveyors of pleasure and knowledge.
The c-word, 'cunt', is perhaps the most offensive word in the English language, and consequently it has never been researched in depth. Hugh Rawson's Dictionary Of Invective contains the most detailed study of what he calls "The most heavily tabooed of all English words" , though his article is only five pages long. According to Francis Grose's scurrilous definition, it is "a nasty name for a nasty thing" As a noun, 'cunt' has numerous other senses: a woman viewed as a sexual object , sexual intercourse, a foolish person, an infuriating device, an ironically affectionate term of address, the mouth as a sexual organ, the anus as a sexual organ, the buttocks, prostitution, a vein used for drug-injection, a synonym for 'damn', an attractive woman, an object or place, the essence of someone, and a difficult task. It can also be used as an adjective to describe a foolish person , a verb meaning both to physically abuse someone and to call a woman a cunt , and an exclamation to signify frustration.
