Saying something like fu, ck in seperate sentences then going I DIDN'T CURSE durrr, is being a complete idiot. Putting it in to two different setences doesn't change the meaning.
When I was a lot younger, I had heard that there were only 'seven' 'curse words'.
I was only able to come up with five:
"bitch",
"ass",
"forget",
"dam", and
"stuff".
Now consider that the meaning of words is constantly changing, some people consider "handicap" a swear word, though it simply means, 'slow', some consider "cigarette" a swear word, though it originally meant a bundle of sticks, or something, some consider "monday" a swear word, when it used to be a commonplace term for black people, even if you weren't particularly tribal.
Once again, there are different languages, and not only do they have their own words, but who says there will be a perfect translation for every word. Possibly other people who speak other languages consider an entirely different set of words 'swear words', that wouldn't even translate to English 'swear words'.
Also, would you ban me for saying "Fu." as a stand alone sentence?
