I looked this up, actually! Got curious and wondered if it was a regional dialect, and the answer is that it sort of is and sort of isn't. So near as I can figure, it first appeared in print around 1910 in Australia and New Zealand. Today, it's very common for Aussies, Kiwis, Brits, and somehow the United States Naval Forces (I'm assuming they picked it up from being stationed at overseas naval bases). So if you are in the US and didn't grow up anywhere near a navy base, it's a crapshoot whether you've heard it before. I grew up next door to a navy base and watched a whole lot of BBC and aussie programming as a child, so it never once occurred to me that the thing I heard all the time in real life and on international television could possibly be a regional dialect. That's what I get for jumping to conclusions, I suppose.
