The Muoriii clip comes from a user-generated soundboard with no documented film, show, game or artist attached, and no verified year of origin. It appears to have spread the way many tiny reaction shouts do: creators needed a half-second dramatic yell for death scenes, failed stunts and prank reveals, and the stretched vowel made it funnier than a plain shout. It now sits alongside other scream meme clips and over-the-top reaction sounds such as the emotional damage meme, used as quick punctuation in edits.
