There was a pub near Henley on Thames called "The Black Boy "---- sadly, due no doubt to political correctness, it is now called "Black Boys Inn " .
    In Her Majesty's Navy, we had various words ,phrases,and expressions for describing people like Matthew Paris ( no relation to Frederick, I hope ??) , none of which I will repeat here.( they are not politically correct ).I will, however, gladly offer some abbreviations, viz. BB, KJ,TB, BH.......
