barf

   [common; from mainstream slang meaning `vomit']

   1. interj. Term of disgust. This is the closest hackish equivalent of
   the Valspeak "gag me with a spoon". (Like, euwww!) See {bletch}.

   2.  vi. To say "Barf!" or emit some similar expression of disgust. "I
   showed  him  my  latest  hack  and  he  barfed"  means  only  that he
   complained about it, not that he literally vomited.

   3.  vi. To fail to work because of unacceptable input, perhaps with a
   suitable   error   message,  perhaps  not.  Examples:  "The  division
   operation  barfs  if  you try to divide by 0." (That is, the division
   operation  checks  for  an  attempt  to divide by zero, and if one is
   encountered  it causes the operation to fail in some unspecified, but
   generally obvious, manner.) "The text editor barfs if you try to read
   in a new file before writing out the old one."

   See  {choke}.  In Commonwealth Hackish, barf is generally replaced by
   `puke'  or  `vom'.  {barf} is sometimes also used as a {metasyntactic
   variable}, like {foo} or {bar}.
