U+81A5 "膥" CJK Unified Ideograph-# Unicode Character

U+81A5 "膥" CJK Unified Ideograph-# is a rare or obsolete Chinese character that is primarily known for its use in Cantonese, where it represents the word for "egg" or "testicle" in a vulgar or informal context. It is formed by combining the radical for flesh or body part (月) with the phonetic component "未" or a related element, though its exact etymology is obscure and it is not commonly found in standard Mandarin texts. This character is notable for its limited usage in regional dialects and its appearance in specialized dictionaries or historical records rather than everyday writing.
