The clip comes from Sonic Unleashed, released in 2008, taken from the Wii version where it plays as one of Sonic's short in-game voice lines during action stages. As game audio was ripped and shared on soundboards, this particular cheer separated from the full game and became a reusable reaction, because it is clean, isolated and instantly readable. It remains popular with gaming editors and Sonic fans who need a quick, character-led celebration that works even without any gameplay footage on screen.
