The phrase is linked to Chilean musician Negro Piñera, whose relaxed public persona helped turn tranquilito perrito into a recognisable catchphrase in Spanish-language meme culture. Short clips of the line began circulating as reaction audio, where creators used it to mock exaggerated panic or to tell an excitable friend to settle down. Its brevity and gentle, teasing delivery have kept it useful for short videos, because the joke is understood immediately even without context, and the playful tone softens criticism into comedy.
