The exact recording behind this clip is not clearly documented, which is common for short reaction sounds passed around soundboards and meme pages. Its strength is the phrase itself, a familiar English put-down for calling someone delusional that needs no context to land. Creators reuse it across gaming clips, commentary videos, and stitch responses because the delivery does the judging for them. As long as reaction humor relies on blunt disbelief, this kind of direct call-out stays in rotation.
