Fast moving thread.
^ Well said, person above.
(Although, oddly, I'm actually in favour of society swearing much, much more. I think it's from years of ineffectually trying to force teenagers to stop swearing in the school/learning context. I think I eventually decided that trying to repress language just leads to bad mental outcomes for people who really do need to express themselves verbally; everyone, to some degree. Although, as Realmz said in there, somewhere, having a better vocabulary is always useful, too. In terms of writing for videogames, I very much like the imperfect characters, so "expressive swearing" would be entirely cool with me.)

Jim Butcher used plough instead of screw or other euphamisms for sex in his Codex Alera series. It actually makes sense in that context because it's an agricultural based society and came from earth before certain acronyms had even come into use.
And yes, the use of the word plough makes sense, but not only in the technological impact on the land, but a more basic function: one has to plough to plant seeds, which then grow into a harvest. Very basic reproduction imagery there. 
That sounds like an interesting read. (I just had a squiz, via Google.)
On a contrasting point to "ploughing", and Minced Oaths, I also really liked "Vashedan" in Origins. (I really can't recall, but Sten said this, right?) I was approaching him in a classic RPG companion kind of a way and trying to make him happy and he hated me. I knew "Vashedan" was a swear, but it had exactly no initial impact, because I've never heard it before. But, it started to grate on me over time, with the added insult of making me feel stupid as well as sweared at.
I'm currently reading The Book Thief, in which a mother calls her adopted daughter "Saumensch" but, because I'm not German, it had initially no impact. It's becoming really clear, however, that Saumensch is a terrible thing for a mother to call her child.
Swearing without swearing (sort of, anyway). That's good writing. (IMO.)
