The sound comes from the musical identity of Predator, the 1987 sci-fi action film starring Arnold Schwarzenegger, with score by Alan Silvestri. Online, short cuts of the theme became popular because they communicate menace and pursuit almost instantly.

It still works well in short-form videos because even a tiny excerpt is enough to evoke the film's tense cat-and-mouse tone.
