The phrase translates from French as he started to dance, and the clip has circulated online as a short, shareable reaction sound rather than as part of a widely documented scene. Its appeal comes from the way a simple narration line can frame almost any dance, making it easy to reuse across memes, edits and short videos. Because it is only a few seconds long, it fits neatly at the start of a clip, and its continued use shows how a small spoken moment can become a running joke for dance reveals and celebrations.
