The phrase comes from Drachenlord, the online name of German streamer Rainer Winkler, whose livestreams and videos have been clipped and remixed by German speaking internet communities for years. Short lines from those appearances are often turned into standalone reaction sounds, and this polite sounding agreement became popular because viewers read it as the opposite of what it literally says. It now circulates in chats, edits and soundboards as a compact sarcastic reply, especially among fans who recognise the voice and the long running jokes around his content without needing any context.
