U.K.: Hey, America you old chap want to play a nice game of Football.
USA: Ok, pal. Let me get my gear and ball.
U.K.: Ok.
A few moments later...
USA: Ok I am done.
U.K.: What the this outfit it is for Rugby!
USA: Dude it's a football outfit. You see football is an oval shape ball. And that ball is soccer.
U.K.: No it's football.
None of them get to play.
Lesson: Learn you should use the correct English when you do to different countries.
My opinion on American English:
A game which you use your feet to play.
U.K.: Football
USA: Soccer
A game which you use your hands to play.
U.K.: Rugby
USA: Football
Conclusion: WTF America?
