Bonjourno is a playful twist on the French greeting bonjour, made memorable by Mister V, a French YouTuber and comedian known for exaggerated delivery and wordplay. Short greeting clips like this one travel easily because they work without translation or context, and fans reuse them as an instantly recognisable hello in edits, streams and social posts. The stretched pronunciation is the joke itself, turning a polite greeting into a small performance, which is why it keeps appearing whenever a creator wants a light, upbeat opening.
