cascade
     
        1.  A huge volume of spurious error-messages output
        by a {compiler} with poor {error recovery}.  Too frequently,
        one trivial {syntax} error (such as a missing ")" or "}")
        throws the {parser} out of synch so that much of the remaining
        program text, whether correct or not, is interpreted as
        garbaged or ill-formed.
     
        2.  A chain of {Usenet} followups, each adding some
        trivial variation or riposte to the text of the previous one,
        all of which is reproduced in the new message; an {include
        war} in which the object is to create a sort of communal
        graffito.
     
        3.  A collection of interconneced networking
        devices, typically {hub}s, that allows those devices to act
        together as a {logical} {repeater}.
