Little is known about the original recording behind this clip, beyond its Portuguese description describing a man shouting miau at an egg. The name miau beninii appears to come from the uploader or soundboard title rather than a film or show. It circulates as a short meme audio, shared for its randomness rather than any context or punchline. Because the yell is brief and instantly recognisable, creators reuse it as a non sequitur reaction, a sound that needs no setup and works precisely because the egg and the scream have no logical connection.
