Cacerolazo comes from the Spanish word cacerola, meaning a cooking pot or saucepan. It names a form of protest where people bang empty pots and pans from homes, balconies and streets to make discontent impossible to ignore. The practice became widely associated with demonstrations in Chile in the early 1970s and later spread across Latin America and Spain during economic and political crises. Online, the same clatter has been shortened into a reusable sound effect for anger, mock protest and exaggerated complaints in edits and memes.
