This clip is tied to Hikakin, a major Japanese YouTuber and beatbox performer whose expressive reactions became widely reused in online edits. Rather than coming from a film or game catchphrase, sounds like this spread through reposts, remix videos and meme compilations, especially in Japanese internet culture. The appeal is simple: the voice is instantly loud, recognizable and exaggerated, so editors use it when a normal reaction would feel too flat. Its staying power comes from that flexible, over-the-top energy.
