Now I've seen this word a couple of times used in RP, and a certain thread triggered this one. The word is very modern in usage and when I see it RPed in this setting it gives me a very silly feeling, it just doesn't fit there to me. I don't know if it's used because of the lack of vocabulary, if so, I don't understand why people don't take a little time looking for some new ones. Does feck mean anything else than fuck? Don't know why it's used instead of fuck, perhaps for a sense of accent or maybe it's a sort of euphemism to squeeze it into RP without letting it look too real life(modern). The setting undeniably uses things from the past and from various cultures where magic hasn't been replaced by technology etc. It's really silly to picture people in such setting saying "fuck you!" to each other when pissed off or whatever. It becomes a parody. Of course there are many other words we use that weren't used in the past and the other way around, but fuck.... is to cross the line IMO.
That's how I personally feel about this subject, but what do you think?
