Online, 'substance' is searched as a meme sound rather than as a clip tied to one widely documented scene, so its appeal comes from how creators reuse it across short-form edits. It circulates as a compact reaction and emphasis sound, passed between meme pages, edit accounts and reaction videos where a brief, confident burst fits a punchline or reveal. That flexibility is why it keeps appearing: it does not need a long setup, it works across different visuals, and it gives editors a quick way to make a moment feel intentional, polished and meme-ready.
