凹凸萌
[āo tū méng]
'Concave and Convex Meng (an expression of being kawaii)' combines elements of quirkiness or imperfection (embodied by '凹凸', which can refer to physical irregularity, unusual personality characteristics, and even unconventional interests) together with '萌'(cute). It suggests embracing uniqueness and not having to meet standard expectations or fit into neat categories but being playful about it, possibly influenced by Japanese kawaii or anime/manga cultures where '萌' also refers to cute and charming.
