This sound is widely shared online under the Russian label "ponos," and it appears on meme pages, chat groups, and short joke edits as a crude reaction effect. Its appeal comes from being instantly understandable even without dialogue: viewers hear it and get the bathroom joke immediately. It is commonly used in the same broad family of lowbrow meme audio as a fart sound, especially in fail edits, food jokes, and deliberately childish humor that aims for shock and embarrassment.
