The clip comes from the voice lines of Team Fortress 2, Valve's class based shooter first released in 2007, and circulated as part of the /v/an sound effects sets shared on 4chan's /v/ board. Those collections pulled short TF2 reactions into soundboards for instant playback during games and threads. A single word answer proved especially reusable, functioning as the positive counterpart to a flat nope when users wanted the opposite reaction. It remains popular because the delivery is unmistakable, energetic, and usable without any setup or context from the original match.
