[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
suits. I'll get back to him on that feature
in my copious free time.
