copious free time (n.): [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."
Went to see Sin City tonight, which is visually stunning and very violent. I'm guessing that the film is a lot more faithful to the original comic books than most of the other comic book adaptations, but I can't say for sure because I've not actually read the original Frank Miller comics.
