The sound is credited to Sylvain Durif and centres on his French phrase meaning it is simply a collective hallucination, a wording that has circulated widely as a short meme clip on soundboards and social video platforms. Because the line is brief and instantly quotable, creators reuse it whenever a claim sounds too strange to accept at face value, especially in reaction videos and commentaries about conspiracy theories. Its deadpan confidence is what keeps it in circulation, turning scepticism into a shared joke rather than a lengthy argument.
