cascade

cascade n.  1. A huge volume of spurious error-message
   output produced 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 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.
