Circulating simply as Know, this clip has no confirmed original film, show or creator attached to its soundboard listings, so its identity comes from how it is shared online rather than a documented scene. The single-word format made it easy to repost, title with one searchable word, and reuse across meme edits where context is supplied by the video itself. Because know can read as agreement, warning or smug confirmation depending on the cut, the clip keeps working in new formats without needing its original source to be understood.

Short clipped voice saying know, used as a dry meme reaction for smug corrections, obvious answers and know-it-all punchlines in short edits.
The clip is just a flat, clipped delivery of the single word know, stretched across a short deadpan beat that makes it sound more like a verdict than a question. There is no music or extra effect behind it, so the emphasis lands entirely on the timing and the slightly smug tone. Viewers read it instantly as someone shutting down an explanation, confirming the obvious, or acting like they knew all along. That dry confidence is why editors drop it right after a reveal, a mistake, or an overconfident claim that collapses.
