Cancelpoodle
Cancelbunny
<messaging> (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".
