bagbiter

bagbiter
 /bag'bi:t.@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 a douche bag or the scrotum (we have reports of
   "Bite the douche bag!" being used as a taunt at MIT 1970-1976, and we
   have another report that "Bite the bag!" was in common use at least as
   early as 1965), but in their current usage they have become almost
   completely sanitized.
