Something that, after viewing V for Vendetta, one may be inclined to talk about doing. Usually said person has no real political agenda, they just thought the movie scene was badass and would enjoy partaking in an equally cinematic experience.

Tim saw V for Vendetta, and for a few days, he seemed preoccupied with the idea of blowing up Parliment.
