The Free On-line Dictionary of Computing (19 January 2023):

cascade

   1.  A huge volume of spurious error-messages output
   by a compiler with poor error recovery.  Too frequently,
   one trivial syntax error (such as a missing ")" or "}")
   throws the parser out of synch so that much of the remaining
   program text, whether correct or not, is interpreted as
   garbaged or ill-formed.

   2.  A chain of Usenet followups, each adding some
   trivial variation or riposte to the text of the previous one,
   all of which is reproduced in the new message; an include
   war in which the object is to create a sort of communal
   graffito.

   3.  A collection of interconneced networking
   devices, typically hubs, that allows those devices to act
   together as a logical repeater.
