Cancelpoodle
     
         (Or Cancelbunny) A manifestation of the
        {Cancelmoose} in the form of a more selective (and probably
        not automated) way to cancel {Usenet} articles.
     
        The term became common during the alt.religion.scientology
        wars of the mid-90s, during which Cancelpoodles were used.
        The "poodle" part is an allusion to one of the parties
        obliquely involved in the fray, who an earlier well-known
        witticism had compared to "a psychotic poodle".
