Americans think all British people speak like Queen Elizabeth, really posh. If they heard me speak they wouldn't know where the hell I was from lol. Britain has got a lot of different accents especially for the size of it. They are so different-

London (cockney)
Scottish
Welsh
Birmingham (Brummy)
Liverpool (scouse)
Yorkshire
Newcastle (geordie)

And many others which I've probably never even heard of.

So Az, which accent is it that annoys you?
