Fuiyoh is the signature catchphrase of Uncle Roger, the character created by Malaysian comedian Nigel Ng. Uncle Roger rose to fame in 2020 with viral videos reacting to amateur cooking, especially egg fried rice, where his exaggerated praise and distinctive accent became instantly recognisable. The word itself is a Malaysian exclamation of amazement, similar to wow, and fans began clipping it for memes, reaction videos and short-form edits. It remains popular because it instantly signals delight and approval without needing any explanation.
