The phrase comes from spoken French, where oh qu'il est bon ce poisson simply means the fish tastes really good, often said with sincere enjoyment at the table. Online, the clip circulates in French speaking meme spaces as a ready made reaction for food videos, shared in short edits and soundboards. Its appeal is not a specific film or show, but the instantly recognisable delivery that turns ordinary praise into comedy. It remains popular because it works without subtitles for anyone who understands tone, appetite and exaggeration.
