   gilley
    n.
       [Usenet] The unit of analogical bogosity. According to its originator,
       the standard for one gilley was “the act of bogotoficiously comparing the
       shutting down of 1000 machines for a day with the killing of one person”.
       The milligilley has been found to suffice for most normal conversational
       exchanges.
