Little is known about the original source of Stinky 2, and its short title suggests it comes from a user-made soundboard collection rather than a widely known film, show or song. That ambiguity has not stopped it circulating as a quick reaction sound in short-form edits, where its value lies less in recognition and more in instant, gross-out comedy. Creators reuse it for smelly jokes, messy reveals and embarrassing moments, often pairing it with a disgusted face or a sudden zoom. Its staying power comes from brevity: it delivers one clear joke and leaves room for the next clip.
