copious free time

copious free time n.  [Apple; orig. fr. the intro to Tom
   Lehrer's song "It Makes A Fellow Proud To Be A Soldier"]
   1. [used ironically to indicate the speaker's lack of the quantity
   in question] A mythical schedule slot for accomplishing tasks held
   to be unlikely or impossible.  Sometimes used to indicate that the
   speaker is interested in accomplishing the task, but believes that
   the opportunity will not arise.  "I'll implement the automatic
   layout stuff in my copious free time."  2. [Archly] Time reserved
   for bogus or otherwise idiotic tasks, such as implementation of
   {chrome}, or the stroking of {suit}s.  "I'll get back to him
   on that feature in my copious free time."
