Gyat emerged as internet slang on TikTok and Twitch, spreading widely in 2023 alongside terms like rizz. Often written as an exaggerated spin on oh my god, it was used by streamers and commenters as a loud reaction to someone attractive, and the phrase oh my gyat became a repeatable joke in comments, livestream clips and edits. Its meaning matters less than its tone now, which is why the shout survives as a standalone reaction sound even outside the original streams.
