Brilliant...
Wonderful. Can't recall where I heard it, but Stephen Fry pointed out the ridiculousness that most swear words are to do with sexual function, as a pleasurable experience. He suggested we use the words 'torturer' or 'rapist' if we really want to insult someone, because there is no possible connotation attached to those words, that is in any way anything other than horrible.
Anecdotally, and I'd probably laugh if I saw this in a book, a friend of mine and I were walking back from a game of football our team had won (Brighton and Hove Albion beat Crystal Palace, but I can't recall the score, since it was in the 80s..) and a Palace 'fan' threw a stone, which my quick-thinking friend plucked from the air, and deposited it over a bridge onto the railway bank. The palace yob, frustrated, yelled from across the safety of the road "You w**ker!", to which my friend put an exagerrated hand to his chin, thought deeply, and called back: "And your point is?" The Palace fan opened his mouth to reply, but couldn't think of a suitable insult to hurl back, so just repeated his previous words. "You've been watching me, haven't you?" called my friend, which sent the palace man incandescent with rage, so he stepped into the road, and got clouted by a police car, that fortunately was only doing about ten miles an hour, but he got up and kicked it in rage, was arrested and bundled into the back of the car. We made it worse by laughing so much we had to support each other, and my friend eventually recovered enough to say "Ah, the perils of imprecation."
This is an hilarious story!!
You have also set me to thinking about why some things are considered foul language, and other probably more horrific things are not considered to be a foul imprecation. Haven't come up with any live insights yet.
