Nigel Ng was born in Kuala Lumpur on 15 March 1991, the son of Chinese-Malaysian parents who also have Hokkien ancestry.

[27] He has released numerous videos critiquing Jamie Oliver's versions of popular Asian dishes such as egg fried rice,[28] Thai green curry,[21] and ramen.

[32] He has also collaborated with numerous entertainers and food personalities including Esther Choi,[33] Joshua Weissman,[34] Chef Rush,[35] Andy Hearnden,[36] Nick DiGiovanni,[37] Steven He,[38] Simu Liu,[39] Jimmy O. Yang,[40] Benny Blanco,[41] Martin Yan,[42] and Gordon Ramsay.

[43] On 22 May 2023, it was reported that Ng's Chinese social media accounts (Bilibili and Weibo)[44] had been closed down in response to perceived criticism of China's government in his stand-up comedy special for the phrase "this Nephew using Huawei phone, they all listening",[45] implying that the Chinese government eavesdrops on civilian phone calls.

[46] On 14 September 2024, as a promotion event for his new restaurant, Ng convened his followers to dress as Uncle Roger outside there.

This event broke the Guinness World Record for "Largest gathering of people dressed as Uncle Roger" with 388 participants.

On the same day, he broke another Guinness World Record for "Most fried rice tossed and caught with a ladle in 30 seconds".

[53][54][55] The accent Ng uses for the Uncle Roger character has received criticism for perpetuating negative stereotypes about Asians.

[21] His critique video of Patel's egg-fried rice has been described as making the viewers "fall for every cultural 'trap' his character sets", overlooking the differences of rice cooking methods in Indian cuisine, and turning East and Southeast Asians into "rice-cooking supremacists" with his "faux encouragement".

[14][64] On 30 July 2023, Ng stated in an Uncle Roger video, "Not all Southeast Asia has good food.

"[65] Cambodia's Ministry of Tourism issued a statement condemning Ng's remarks as damaging to the image of its cuisine and demanding an apology.

[73] At the end of 2024 announced he was engaged to Sabrina and proposed to her in Japan during the sakura festival, restating he was living in Los Angeles.
