“Zamknij mordę” is a Polish phrase used online as a blunt reaction audio, especially in short meme edits, chat jokes and reposted soundboard clips. The phrase is vulgar, closer to “shut your mouth” than a polite request to be quiet. Its exact recording source is not clear from the available information, which is common for short viral voice snippets shared across messaging apps and meme pages. It stays popular because the line is brief, instantly readable to Polish speakers and easy to drop as a comedic interruption.
