crawling horror

from Jargon File (4.4.4, 14 Aug 2003)
crawling horror
 n.

   Ancient crufty hardware or software that is kept obstinately alive by
   forces beyond the control of the hackers at a site. Like {dusty deck}
   or {gonkulator}, but connotes that the thing described is not just an
   irritation but an active menace to health and sanity. "Mostly we code
   new stuff in C, but they pay us to maintain one big FORTRAN II
   application from nineteen-sixty-X that's a real crawling horror...."
   Compare {WOMBAT}.

   This usage is almost certainly derived from the fiction of H.P.
   Lovecraft. Lovecraft may never have used the exact phrase "crawling
   horror" in his writings, but one of the fearsome Elder Gods that he
   wrote extensively about was Nyarlethotep, who had as an epithet "The
   Crawling Chaos". Certainly the extreme, even melodramatic horror of
   his characters at the weird monsters they encounter, even to the point
   of going insane with fear, is what hackers are referring to with this
   phrase when they use it for horribly bad code. Compare {cthulhic}.
