Verb. To put a spin on an old cliche to make it seem more original to your audience. Usually the spin is ridiculous and idiosyncratic, but sometimes it can totally redeem a passage.

The term comes from the old cliche of a spy cutting through the rope (s)he is caught up in with a knife that (s)he finds in her pockets that the guards did not pat down correctly. A writer might put a spin on the old cliche by having the spy vomit up the knife, thus making it at least somewhat original.

Writer 2: Tell me about it.
