Rainer Winkler is a German streamer and YouTuber widely known online as Drachenlord, whose loud, confrontational videos and streams have made him a long-running figure in German internet culture. Clips of him losing his temper, described in German as rastet aus, are shared as short reaction sounds because the anger is immediate and easy to recognise even without translation. They circulate in meme edits and gaming videos alongside other scream meme clips, and remain popular because they give creators a ready-made burst of frustration for moments that go wrong.
