This clip is best understood as a general internet reaction sound rather than a clearly documented quote with a reliable single origin. Short "damn" or "dammmn" reactions have circulated for years across meme edits, repost pages and short-form videos because the meaning is instantly clear. Creators keep using this version when they want a quick hit of disbelief, admiration or mock shock without needing extra setup. Its staying power comes from how easily it fits roasts, wins, reveals and sudden visual punchlines.
