The sound comes from Game Grumps, the long running Let's Play duo of Arin Hanson and Dan Avidan, whose exaggerated reactions have been clipped for soundboards for years.

It spread through gaming edits, Discord servers and meme compilations as a shorthand for perfect or ironically perfect, and it remains popular because the delivery sells both meanings instantly.
