This audio is mainly known through short-form meme edits rather than a clearly credited mainstream source in the provided data. It appears in enemy-themed videos, especially John Pork joke posts, where the line is used as a dramatic accusation or reveal. The format spread because it is simple and instantly readable: one short phrase, then a visual payoff. Creators still use it when they want a quick suspicious tone without needing a long setup, much like other reaction-ready meme sounds such as an evil laugh.
