Southerners have no idea what a british accent sounds like.
I am from Texas, the most stereotyped place of hicks," steers, and queers"
In my whole life(14 years old) there is only one person I've ever met that had a hick type accent. That was my English teacher last year. That's IT.
I know when someone is British or not.
Me personally, I love the Scottish and Irish accent. It is just so epic.
