Cacerolazo is a long-standing form of protest across Spanish-speaking countries, in which participants bang pots, pans and other kitchen utensils to make a collective noise that cannot easily be ignored. The name comes from cacerola, the Spanish word for a cooking pot, and the practice is closely associated with street demonstrations in Colombia and elsewhere in Latin America. A clip labelled for Tunja, the capital of Boyacá in Colombia, fits that tradition, and its brief, percussive burst makes it easy to reuse online as shorthand for a crowd protesting together.
