No specific original source is documented for That Was Rude, and the clip circulates mainly as a detached reaction sound rather than a scene people quote from a film or show. It spread through TikTok and soundboard shares, where short, clearly worded voice lines travel easily between unrelated videos. Its appeal is how universal the situation is, from sibling teasing to gaming lobbies and comment-section callouts, so creators keep reusing it whenever a moment needs a quick, recognizable judgment without a long explanation or setup from the poster themselves today.
