    Septic

    Cockney rhyming slang for a yank, a person from the USA. The term originates from the phrase “septic tank”, the second word rhyming with yank.

    Cockney rhyming slang originated in the East End of London around the 1850’s. Rhyming slang phrases are created by taking a common expression that rhymes with the intended word and then using either the whole expression or just the first word to replace it. For example, the word “butcher’s hook” rhymes with “look”. “Having a look” therefore becomes “having a butcher’s” in rhyming slang.

    It remains a matter of speculation whether rhyming slang came about by accident or whether it started as a secret language developed intentionally to allow market traders to collude or criminals to confuse the police.

    Example usage:

    “That septic thinks I give a shit about baseball, but he’s mistaken”.
