dogpile

dogpile
 v.

   [Usenet: prob. fr. mainstream "puppy pile"] When many people post
   unfriendly responses in short order to a single posting, they are
   sometimes said to "dogpile" or "dogpile on" the person to whom they're
   responding. For example, when a religious missionary posts a
   simplistic appeal to alt.atheism, he can expect to be dogpiled. It has
   been suggested that this derives from U.S. football slang for a tackle
   involving three or more people; among hackers, it seems at least as
   likely to derive from an `autobiographical' Bugs Bunny cartoon in
   which a gang of attacking canines actually yells "Dogpile on the
   rabbit!".
