Allez is a common French word of encouragement, roughly meaning come on or go for it, and Nono is used here as the name being cheered on. This second version circulates online as a short reaction clip rather than as a song or a scene with a widely documented source. French speaking users share it in chats and edits, and other viewers pick it up from the tone alone, even without understanding every word. Its appeal is the contrast between sincere sounding support and an obviously silly situation.
