The phrase comes from Mexico's 2006 presidential campaign, when candidate Andrés Manuel López Obrador told sitting president Vicente Fox ya cállate chachalaca during a dispute over campaign advertising. The line was widely replayed on television and radio and became one of AMLO's most quoted early catchphrases. A chachalaca's loud dawn calls made the nickname stick in popular culture. Years later the recording resurfaced in memes, remixes and WhatsApp audios, where Spanish speakers reuse it as a humorous way to end noisy arguments.
