Drachenlord is the online name of German streamer Rainer Winkler, whose videos and livestreams have been heavily remixed in German meme culture for years. Short clips attached to his name travel widely on soundboards and in edit communities, even when the audio itself is a simple effect like this siren. The 'laut' in the title is German for loud, and that is the point of the clip's appeal. It has become a reusable alarm gag for warnings, raids, fails and mock emergencies online.
