The 'Flat Is Justice' (Japanese: Heimen wa Seigi) and 'Delicious Flat Chest' memes are long-standing slogans within the anime and otaku community used to express a preference for petite, slender character designs over more curvaceous ones. Originating in Japanese image boards like 2channel and Pixiv before spreading to Western sites like 4chan and Reddit, the phrase acts as a rallying cry for fans of the 'pettanko' archetype. It is often used humorously in online debates to assert that smaller proportions are aesthetically superior or more 'just' than the alternative. Over time, the phrase has been paired with various anime characters and used in image macros to signal a specific subcultural niche, often appearing in contexts where character design and tropes are being playfully argued.
