This clip circulates mainly as a short reaction sound on meme soundboards and in short-form video edits, where the search phrase smells like meme points to its use as a quick setup for smell jokes. Because it is only a couple of seconds long, it is easy to drop into a scene without interrupting the action, and its open-ended question leaves room for a visual punchline. That flexibility is why creators keep reusing it for everyday gross-out moments, from bad food and messy rooms to awkward encounters, rather than tying it to one specific clip.
