[Again I delve into profanity. See this for my last effort on this topic.]
There is no doubt what the foulest word in the English Language is. As a hint: it starts with the letter "C".
I must admit, I have occasion to use this word, usually when behind the wheel of my Honda Civic, when discussing the merits of Channel 9 TV personalities, or when discussing telephone companies. Never in front of the children of course (unlike my mother who used it in front of me). But it is strongly frowned upon when I use it in the home, for whatever reason. When I do let it slip out, I hear the "C-Word signature" cough from my Chick. She does not like hearing it.
It sounds a little like "hup-hrrm", but in a coughy way.
"Gee that Eddie Macguire is a bit of a c..."
You get the picture. I've worked out that the cough is not because of any liking she has for Eddie Macguire, either.
Today, I got the "C-word signature" cough for another reason. I was in the office/spare room, listening to Mozart whilst working, she's in the loungeroom listening to a Charlie Parker CD. I reckon Charlie is OK, but, waggishly, while returning the Mozart CD to it's rightful place in the bookshelf in the loungeroom, I attempted to get a small rise out of her:
"<big smile>What's this sh*t you're listening to?"
I think if you analyze it carefully, you will realise, as I did, that she has used the C-word on me!
