The line comes from Metal Gear Solid 2, the 2001 stealth game in the Metal Gear series, where the character known as Iroquois Pliskin is tied to the Solid Snake identity that other characters keep questioning. Fans clipped the denial and shared it on soundboards, where its short, emphatic correction made it easy to reuse outside the game. It spread through gaming edits and reaction videos as a shorthand for calling out a lookalike or a false claim, and it remains popular because the joke needs no knowledge of the full plot to land.
