bagbiter

bagbiter: /bag'bit-*r/ n.  1. Something, such as a program
   or a computer, that fails to work, or works in a remarkably clumsy
   manner.  "This text editor won't let me make a file with a line
   longer than 80 characters!  What a bagbiter!"  2. A person who has
   caused you some trouble, inadvertently or otherwise, typically by
   failing to program the computer properly.  Synonyms: {loser},
   {cretin}, {chomper}.  3. `bite the bag' vi. To fail in some
   manner.  "The computer keeps crashing every five minutes."
   "Yes, the disk controller is really biting the bag."  The
   original loading of these terms was almost undoubtedly obscene,
   possibly referring to the scrotum, but in their current usage they
   have become almost completely sanitized.

   ITS's {lexiphage} program is the first and to date only known
   example of a program *intended* to be a bagbiter.
