“Fuyoh” became strongly associated with Uncle Roger, the Malaysian comedian character created by Nigel Ng and popularized through viral YouTube reaction videos in 2020. The expression spread across TikTok, Shorts and meme edits as a fast way to signal impressed approval, especially around cooking content and dramatic reveals. Its staying power comes from how short and recognizable it is: one word, clear delivery, and an instantly memeable tone that fits reaction clips, parody edits and celebratory punchlines.
