The exact origin of this clip is not widely documented, so it circulates mainly as a standalone reaction sound shared on soundboards and in short form edits. Its popularity comes from the universal setup behind the line, where claiming not to know someone becomes a quick punchline for embarrassment, bad behavior or unwanted association. Because the recording is only a second long and the wording is instantly clear, creators reuse it as a drop in meme videos, gaming clips and group chat replies without needing any context from a film or show.
About this sound
A short voice clip of someone saying I don't know this guy, used as a reaction sound effect for awkward meetings, mistaken identity and disowning friends.
This is a brief, deadpan voice clip of a man flatly saying I don't know this guy, delivered like he is distancing himself on the spot. The line lands quickly, with a casual, slightly dismissive tone that makes it feel like an instant denial rather than genuine confusion. Played over a photo, introduction or embarrassing moment, it instantly frames the other person as a stranger, a liability or someone too cringe to claim. The humor comes from how blunt and effortless the rejection sounds, turning a normal social moment into a joke about pretending you have never met someone.
