The line comes from a short Thai meme song that took off online, built entirely around the playful proverb that even a donut has a hole. Shared as a bite-sized audio clip, it became a staple of Thai meme culture: the goofy, chantable hook works as a punchline for fails, pranks and silly confession videos. Because the phrase doubles as gentle teasing — implying someone missed the obvious — creators keep reaching for it whenever a clip needs a lighthearted jab. Its popularity endures thanks to that mix of catchy melody and universal, silly logic.
