With no clear single source attached to this short clip, it circulates online as a generic reaction sound rather than a quote from a specific show, film or creator. That flexibility is part of its appeal, since editors can drop it into almost any surprising moment without needing viewers to recognise where it came from. It sits alongside other short reaction clips such as an anime wow, and it is commonly reused in memes, reaction videos and short-form edits where a fast, unmistakable expression of surprise does the work of a longer explanation.
