The phrase bonjour maître is a formal French greeting that translates to hello master, and its humour online comes from using such deferential language in casual situations. The short clip has circulated on soundboards as a reaction sound, shared for edits, gaming moments and chat jokes where someone wants to sound overly eager to help. Because it is only a few seconds long and instantly understandable even to non French speakers, it works as a quick punchline without needing setup or context from a longer scene.
