Definition

Adjective: - Forgetful, absent-minded, scatterbrained: Describes a person who is prone to forgetting things, often due to carelessness or a lack of attention. It is an informal, slightly vulgar term. - Having a "scrambled" or "foggy" liver (figurative): The term is a compound where "lú" means confused/befuddled and "gan" means liver (considered the seat of courage and spirit in Vietnamese culture), creating an image of someone whose mental faculties (spirit/courage) are muddled, leading to forgetfulness.
