Liu Kang is one of the central heroes of the Mortal Kombat fighting series, and Mortal Kombat: Deception was released in 2004 as the sixth main entry. The scream comes from his in-game defeat and knockdown vocals, the kind of short, strained yell fighting games used to sell a heavy hit. Clips like this were later lifted from gameplay and shared on soundboards, where short character reactions are easy to reuse. It survives because the sound is instantly recognisable as a fighting-game defeat, yet exaggerated enough to work as a joke in edits, streams and reaction videos.
