This clip has no confirmed original source; it circulates online as a standalone stock-style cheer rather than a line from a film, show or game. Sounds like it appear in meme edits and reaction compilations where a quick vocal burst of joy is needed, and its one-second length makes it easy to drop into fast-paced edits. Over time it has become a generic celebration sting used by creators who want a lighthearted, cartoonish reaction without any recognisable character or dialogue attached to it.
