The phrase is German slang for asking whether someone has had a stroke, used here as an exaggerated reaction rather than a medical statement. Online, the clip is associated with the German streaming scene around Hänno, also known as HandOfBlood, and it circulates on soundboards alongside other short reaction lines from German creators. Its appeal is the blunt, instantly understandable insult, which translates even for viewers who only catch the tone. Because it is under two seconds long, it is easy to drop into edits, streams and memes without interrupting the flow.
