British cockney rhyming
slang for a Yank (a Yankee, an American). As in 'Septic Tank Yank'. I'
m told by my British
friends the origin of this was the British military, where in WWI American infantrymen exhibited the worst of the worst language, and talked a lot of crap. But being from California, I remind them that I'
m about as Yankee as an Australian is a Brit. Calling everyone in America a Yank is really ignorant. The British say Septic, while Australians generally say Seppo (compounded ignorance).
