Sure, Miia--I'll be glad to help; it sounds very interesting. Several years ago, there was a British clerk in the office where I worked, and one day I asked her whether our "f**k" was more or less the equivalent of their "bloody". She was deadpan at the first word but her eyes widened at the second one, just as above I couldn't bring myself to spell out our word but had no trouble with the British one.
Oh, yes--it was very intelligent of you to find this place and seek respondents!
