Joe Dassin was a French-American singer who became one of France's most popular pop voices in the 1960s and 1970s, known for smooth, melodic hits that remain widely recognised today. Short vocal moments from his recordings have since circulated online as meme sounds, stripped of their original verses and reused for humour rather than nostalgia alone. The repeated zai phrase works because it needs no translation, making it easy to drop into edits across languages and helping a brief retro vocal stay in circulation on social platforms.
