“Fuiyoh” is closely associated with Uncle Roger, the comedy character created by Nigel Ng, who became widely known online through food reaction videos. The catchphrase spread across short-form clips, reposts and meme edits because it delivers instant approval in a funny, recognizable way. It stays popular in cooking content, reaction compilations and ironic edits where creators want a fast, upbeat response. Fans often pair it with other exaggerated reaction sounds such as oh my god, wow! to heighten a reveal or punchline.
