Insult comedy is a comedy genre in which the act consists mainly of offensive insults, usually directed at the audience or other performers. Typical targets for insult include people in the show's audience, the town hosting the performance, or the subject of a roast. The style can be distinguished from an act based on satire, or political humor. Insult comedy is often used to deflect or silence hecklers even when the rest of the show is not focused on it.
