Osuruk sesi simply means fart sound in Turkish, and clips with this label circulate widely on soundboards, meme pages and chat groups rather than from one famous source. People use it as a fast joke cue in short edits, prank audios and reaction posts, much like a wet fart sound or other exaggerated toilet humor effects. Its staying power comes from being instantly understood across languages: even without dialogue, the joke lands the moment the noise plays.
