Well 'fuck' is in such common use that it has really lost its impact I think. However the 'C word' still has delicious shock value. I am thinking about Hit Girl using it before an orgy of killing in Kick Ass. And I heard a very smartly dressed man in a business class seat on a flight refer to his mobile in a very loud voice as a 'cunting phone!' But he was English and we definitely use that word more than my friends in the States do. P.S sorry for hideously late reply but I am new to Steemit and didn't see your comment until just now. Don't want you to think I am a total fucking cunt!!
