Nein is the German word for no, and this clipped shout is tagged as coming from Age of Empires, where short voice taunts are shared between players during matches. Taunt clips like this moved easily from games onto soundboards and meme pages because they are brief, recognisable and need no context. The harsh delivery made this one a staple for comic refusal online, and it is still dropped into edits and streams whenever a plain no would not be dramatic enough for the moment.
