Enjoyable as it is to use them in place of spaces I tend not to, however I am certainly not above swearing and find it hilarious when people get offended. When speaking I have a very dry, not terribly loud, somewhat monotone voice and word choice not entirely dissimilar to that which I might use in text, combining to see people falsely assume I am not an uncouth bastard. To that end precision guided/tactical is my favoured method, actually no saying cunt in front of Americans and pretending that I do not know that is not the rather more mild invective that it is here and most of the rest of the English speaking world is my absolute favourite.
Would be EOF so song
