The yell is tied to the Mortal Kombat fighting game franchise, where the name is famously shouted in a theatrical announcer voice. That delivery became memorable to players and spread beyond the games into edits, compilations and versus memes online. It still gets used because the reference is immediate even in a very short clip: one shout can signal combat, rivalry and exaggerated stakes. In meme culture, it fills a role similar to a FNAF Jumpscare Scream or an Inception Button for instantly heightening tension.
