Many years ago,a Boro-lad I know, got involved in a fracas with the local constabulary whilst visiting London. Safe at home in the Boro with some decent beer betwaddling his faculties, the story may well have been embellished somewhat but he reckons the Cockney Bobbies addressed him rather unkindly along the lines of you expletive Geordie expletive ,you expletive Geordie expletive and, even,you expletive Geordie expletive!
