person of no account
     
        (University of California at Santa Cruz) Used when referring
        to a person with no {network address}, frequently to forestall
        confusion.  Most often as part of an introduction: "This is
        Bill, a person of no account, but he used to be
        [email protected]".
     
        Compare {return from the dead}.
