The origin of this Stinke clip is not clearly documented, so its life online is better defined by how it is shared as a quick reaction sound. The I don't know line circulates on soundboards and in short edits where a short, recognisable response is more useful than a long explanation. Its appeal comes from timing rather than context, allowing creators to reuse it across chats, streams and comedy cuts whenever confusion, forgetfulness or deliberate evasiveness fits the moment better than a serious answer.
