Given how often the semi nude famale body is shown in the UK tabloid press and tv it is hard to believe that tits is taken as very offensive over here I believe that more offence is taken in the USA as in the example of their changing titbit to tidbit The word titbit carries no offence whatesoever in the UK and Titbits was the name of a general interest UK magazine for many years Tits is only a very mild and slightly comical expletive in UK use The word piss is more vulgar but can be found in the Bible It might be heard in the matey environment of a pub such as Joe has gone for a piss It has more vehemence in piss off but with less weight than the good old Anglo Saxon fuck off As regards what the public take as swear words even get stuffed might be classed as such yet there is stuff in everything
