Many years ago, I heard a former athlete (now a sportscaster) providing a running commentary during a basketball game. He cried out, "It's really hotting up in here!" At the time, I attributed this odd turn of phrase to the fact that he was, after all, a former athlete and forming a complete sentence was about all that could be expected of him. Later, I discovered that this is a valid expression in the UK and that I, as a relatively illiterate American was wrong to mock him.
I still think, however, that his usage was not due to his extensive global awareness but was instead caused by stark raving idiocy.
