Soramimi Cake is the iconic opening theme for the 2002 anime series Azumanga Daioh, performed by Oranges & Lemons. The title itself is a play on 'Soramimi,' which translates to 'mishearing' or 'phantom hearing,' perfectly reflecting the nonsensical and dreamlike nature of the lyrics. In internet culture, the song and its associated visuals—often featuring the character Osaka staring blankly or the cast floating in surreal environments—have become synonymous with early 2000s 'brain rot' and aesthetic nostalgia. The meme is typically used to represent feelings of confusion, whimsical detachment from reality, or simply to celebrate the chaotic charm of the slice-of-life genre.
