Most of my Friends overseas are Brits mostly Mancunians. So anything I understand about British English comes from them.
My big problem with the Mancs is that they mumble with their heads down and a little turned away from you. They tell me thats a head butt (Glasgow kiss) defense. The dudes from London all sound like BBC presenters, my Manc friends tell me thats because they learned to speak English from a guy named Jimmy Saville. Plus, they remind me that lots of folks in London arent really human, like "Gooners" and "Hammers" and that there is an area in London called Millwall where all the bestial degenerates they forgot to ship to Australia have reproduced.
I have always had a problem understanding the Welsh dudes, especially when drunk. My friends say thats because they learn to talk with sheep guiding them into manhood. And then there are Geordies? is it, and supposedly they are retarded.
I have trouble with Scots too, I have to use subtitles when watching Trainspotting. My friends tell me Jocks havent been truly civilized yet.
And then Liverpool. I listen to some of them on footy shows and I get lost. My Manc friend told me thats because they arent speaking English but instead, a language known as Scouse, which is a seperate language born in Council Houses. He said Liverpool is not really a part of England, for example they have their own holidays like Giro Day.
I get ragged to death of course, if I say I have to take a p**s, they say, where ya taking it.
