Cacerolazo, from the Spanish word for saucepan, is a long-standing form of protest in Latin America and Spain in which people bang pots and pans to make their dissent heard without gathering in one place. The practice became widely recognisable during large street demonstrations, where its metallic rhythm could be heard from balconies and side streets alike. Online, short recordings of that rhythm are now reused in protest compilations, political commentary and satirical edits, because the sound alone immediately evokes a crowd, a cause and a public demand for attention.
