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.
