The phrase is German for they are not welcome here, with Viecher suggesting creatures regarded as pests or nuisances. No clear original film, show or creator is documented for this short recording, so it circulates mainly as a standalone reaction clip on soundboards. Its appeal comes from the severe delivery and the instantly understandable meaning, even for viewers who translate it loosely. German-language meme edits use it to reject characters, animals or intruders, and its brevity makes it easy to insert into short videos without explanation or setup.
