Well fuck me! I did not know that. I used "Fuckin A!!" in a PM to a fellow 'Cat in the eastern US a while back in the Eastern Canuck sense, that is, to express my great joy toward his good news. By return PM, he expressed deep concern and puzzlement about why I had called him a Fuckin Asshole. Perhaps I should have used the modern, "Absofuckinglutely Excellent!"
