Long scream clips like this one circulate on soundboards and in meme edits because a held aaaaaahhhhhhh needs no language or context to be understood. The format became a staple reaction sound as short form video grew, with creators reusing the same exaggerated yell for jumpscares, fails and dramatic reveals. Its length of a few seconds makes it easy to loop, layer or cut short, and that flexibility has kept it in regular use even though its original recording source is not clearly documented in the clip itself.
