The exact recording behind the khyii clip is not documented, which is common for short sounds that surface on user generated soundboards. The label comes from the Thai verb ขยี้, widely used online to mean dunking on or roasting someone, and that meaning shaped how creators adopted it: as a compact reaction sting for comebacks, fails and teasing moments in short form video. Its three second length makes it easy to slot into fast edits, which is why it keeps circulating as a meme punctuation mark rather than fading away.
