The “haiya” sound is closely associated with Uncle Roger, the comedy character created by Nigel Ng. The character became widely popular on YouTube in 2020 through reaction videos about cooking, where “haiya” turned into a repeated expression of frustration and disbelief. The clip spread into TikTok, reels and meme edits because it is short, clear and instantly readable. It remains popular as a fast reaction sound for food content, cringe posts and fail compilations, much like emotional damage meme in the same comedy style.
