The 'I Really Want Some Miso Soup' meme stems from the viral craze surrounding the anime My Deer Friend Nokotan (Shikanoko Noko Noko Koshitantan). The phrase caught fire on social media, particularly TikTok and Twitter, due to its catchy, repetitive nature and the character’s quirky obsession with the traditional Japanese dish. It is widely used to express sudden, intense cravings for specific foods or to capture the feeling of being hyper-fixated on a minor desire. The meme blends the world of 'brain rot' internet humor with wholesome anime aesthetics, making it a go-to template for relatable, hungry moments.
