TF2 MeeM circulated as part of the long running Team Fortress 2 community humour, where short Spy voice clips were remixed, distorted and reused across fan videos and soundboards. The exact first upload is not widely documented, so the sound is best known through its repeated use rather than a single source clip. Its appeal comes from how recognisable the voice remains despite the silly distortion. It continues to appear in gaming edits because a familiar TF2 line can signal a joke instantly, even to viewers who only know the character from memes.
