My best friend’s father growing up served in Patton’s Third Army. When they encountered their British brothers-in-arms, they would be greeted with “’ey, Yank, got ah fag?” The Brits knew what they were saying, they just liked to tweak the Yanks, who actually were replete with tobacco. I worked with a guy who had previously worked for a U.S. company that had a plant in Britain. The secretary would call his home in the U.S. and tell his wife to “Have Joe knock me up when he’s over here.”, meaning in British “visit me”, but she knew what it meant in American.
