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