Elmo is the small red puppet from Sesame Street, and his high, excitable voice has made short clips of him a staple of meme soundboards. This flying scream fits that tradition because it is instantly recognisable even without any picture, carrying panic and silliness in a single drawn-out note. Meme creators reuse it for launches, falls and surprise knockbacks, where a familiar children's character voice makes the gag feel harmless and absurd. Its brevity also helps, since the whole joke lands in under four seconds and can be dropped into almost any short video.
