   U. S.] --Halliwell.
   [1913 Webster]

from Jargon File (4.4.4, 14 Aug 2003)

chomp
 vi.

   1. To {lose}; specifically, to chew on something of which more was
   bitten off than one can. Probably related to gnashing of teeth.

   2. To bite the bag; See {bagbiter}.

   A hand gesture commonly accompanies this. To perform it, hold the four
   fingers together and place the thumb against their tips. Now open and
   close your hand rapidly to suggest a biting action (much like what
   Pac-Man does in the classic video game, though this pantomime seems to
   predate that). The gesture alone means `chomp chomp' (see Verb
   Doubling in the Jargon Construction section of the Prependices). The
   hand may be pointed at the object of complaint, and for real emphasis
   you can use both hands at once. Doing this to a person is equivalent
   to saying "You chomper!" If you point the gesture at yourself, it is a
   humble but humorous admission of some failure. You might do this if
   someone told you that a program you had written had failed in some
   surprising way and you felt dumb for not having anticipated it.
