Do you really use words like "beastly", "jolly" and "poopy" in your normal everyday conversations?
I have to be honest and tell ya that I've never seen, let alone read, those words used beyond reading Enid Blyton books (with the possible exception of "poopy"). And i find 'em quite strange to see and read.
Folks from Lancashire dont talk like that- we'd get our heads kicked in if we did.
