Neural Flatus: Agents Provocateurs

Last night, just as I was about to climb in bed, I started saying <<agents provocateurs>> in a horrendous, overly-dramatic French accent. For whatever reason I had it in my head that this phrase referred to spies, but nope. These are people who stir up trouble in order to incriminate or discredit other folks. Where the hell in left field did this one come from?
