With no clear single source attached to this short clip, listen yeah has grown mainly through reuse in memes, reaction videos, and short-form edits, where its two-word agreement is easy to recognise and drop into almost any context. Its appeal comes from its simplicity: it does not need a setup, a character, or a punchline of its own, so creators can use it to agree, hype, or underline a moment without slowing a video down. That flexibility is why it keeps appearing in new edits long after its first uploads.
