The phrase is Russian slang for asking who defecated, and online it circulates mainly as a short, shareable voice clip rather than as a line tied to a widely known film, show or song. Its appeal is deliberately crude and universal, since almost everyone recognises the awkward moment of blaming someone for a bad smell. On soundboards and in short-form videos it is used as a standalone reaction, often without translation, because the tone and context make the meaning clear enough for the joke to work across languages.
About this sound
A Russian voice clip asking who pooped, delivered in a blunt comedic tone and used as a reaction for smelly, awkward moments in memes and short videos.
This short Russian voice clip centres on one blunt question, who pooped, spoken in a direct, slightly accusatory tone that makes the joke land instantly even for listeners who do not understand Russian. The delivery is plain and unadorned, with no music or effects to soften it, so the humour comes entirely from the timing and the embarrassment of the accusation. It works as a sudden punchline, turning an ordinary scene into something gross, awkward and funny, and it is especially effective when paired with a confused reaction, a bad smell or a character trying to deny responsibility.
