The origin of Eahoughw is not documented, and the name itself appears to be a phonetic spelling of the noise rather than a reference to a film, game or show. It circulated as a short soundboard clip, shared mainly for its randomness, and picked up use in meme edits where a meaningless vocal reaction is funnier than a clear line. Its appeal has lasted because it fits many situations without context, similar in spirit to other random reaction sounds that creators drop in for instant absurdity.
