n American: Hey, did you hear Bob had moved to New York and married a septic? From Cockney rhyming slang “septic tank” / “yank,” where “yank” is in turn used in the U.K. to mean “American.” If you don’t believe me, look it up, but I have to warn you that I also wrote that definition. The Australians use the same term and have further abbreviated septic to “seppo.”
