chomp
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.
