Gyatt became a widely used piece of internet slang for an exaggerated reaction to someone attractive, spreading through streaming, TikTok and meme edits before reaching VTuber fan communities. This version centres on Oozora Subaru, a member of Hololive, whose energetic delivery fits the joke and makes the clip easy to reuse. Fans began sharing it in short edits, reaction videos and compilations, where a single shouted word can signal surprise without needing extra context. Its popularity has lasted because the reference is instantly recognisable to viewers who follow VTuber and anime meme culture.
