The phrase comes from Austrian spoken German, where Fressen is a rough, animal-like word for eating, which makes the request sound greedier than a normal Essen. Online, the clip circulates as a short reaction sound rather than from a widely credited film or show, shared on soundboards and in meme edits. Its appeal is the mix of dialect, impatience and pure appetite, so creators reuse it whenever a person or animal acts obsessed with food. It stays popular because the meaning is clear from tone alone.
