This clip is widely used online as a generic confusion reaction sound rather than for a clearly documented character or scene. Short “what” or “wut” samples spread easily on meme pages, short-form videos and soundboards because they are fast to drop into edits and instantly readable. Its appeal is the same reason creators also use sounds like vine boom sound or asian meme huh: one tiny audio cue can signal disbelief, confusion or secondhand embarrassment without stopping the pace of the video.
