Vilebrequin is known as a French car-comedy YouTube presence, and this clip is tagged directly to that name. The “Poulala” moment sounds like a spontaneous in-video reaction rather than a song, sketch punchline or film quote, so it circulates mainly as a short reaction excerpt. French car fans repost this style of exaggerated exclamation because it fits dyno runs, project-car disasters and banter-heavy edits. Its continued use comes from that narrow but durable niche: instantly signaling amused disbelief in automotive meme culture.
