Usage

What does riot mean? A riot is a situation in which people in a crowd are engaging in violence and/or destruction in the streets or another public space. Riots often involve two or more groups fighting, or one group causing destruction. Riot can also be used as a verb meaning to participate in a riot. Members of the crowd who do this can be called rioters. The word rioting can be used as both a verb and a noun. Violent protests are sometimes called riots. But the term riot is often extremely loaded and used in a way that’s intended to be dismissive of protests and portray protesters as lawless, destructive, or violent. Specifically, the term has been frequently used to portray African American protesters in this way, such as during mass demonstrations. For example, one may try to discredit a protest by calling it a riot or to discredit protesters by calling them rioters. This especially happens when people conflate a protest with other things happening around it, such as looting. The word riot is also used in a much different way to refer to something very funny, especially in the phrase laugh riot. The term implies that it results in intense, unrestrained laughter. Example: The riot outside the stadium left dozens of people injured, along with widespread damage to cars in the parking lot.
