The exact recording behind this clip is not documented, which is common for short user-uploaded prank sounds that circulate on soundboards under noisy titles like this one. The 'ourrrr' label describes the vocalization itself rather than a known character or show. Clips of this type spread because they are short, loud and instantly usable, often saved for jump-scare pranks, reaction memes and playful animal-voice dubs. With only a couple of seconds of audio, it fits easily into vertical video edits where a sudden burst of noise does most of the comic work.
