Pukan is the Russian slang word for a butt and for farting, and this clip circulates on soundboards simply labelled as another fart recording with no known film or show source. Short fart effects like this have been passed around prank culture for years, from hidden speakers to early meme videos, because the sound needs no translation. Its one second length makes it easy to reuse in edits, chats and livestreams, where it still works as a universal, childish joke.
