Here is the definition of charivari by Wikipedia:
' Charivari (or shivaree or chivaree, also called "rough music") is the term for a French folk custom in which the community gave a noisy, discordant mock serenade, also pounding on pots and pans, at the home of newlyweds. The loud, public ritual evolved to a form of social coercion, for instance, to force an as-yet-unmarried couple to wed. This type of social custom arose independently in many rural village societies, for instance also in England, Italy, Wales or Germany, where it was part of the web of social practices by which the small communities enforced their standards.
The community used noisemaking and parades to demonstrate disapproval, most commonly of "unnatural" marriages and remarriages, such as a union between an older widower and much younger woman, or the too early remarriage by a widow or widower. Villages also used charivari in cases of adulterous relationships, wife beaters, and unmarried mothers. In some cases, the community disapproved of any remarriage by older widows or widowers. Charivari is the original French word, and in Canada it is used by both English and French speakers. Chivaree became the common spelling in Ontario, Canada. In the United States, the term shivaree is more common.[1]
