Un entonnoir has circulated online mainly as a short French meme sound, passed between creators who enjoy its odd, quotable phrasing rather than any single viral video. Its appeal lies in the way a plain everyday word can become a running joke when it is repeated out of context, and that flexibility has helped it survive beyond its first shares. Editors now use it as a quick audio punchline, while listeners recognise it instantly as a signal that something deliberately silly is about to follow.
