闺女稍息跟爹混儿子立正跟娘混
[guī nǚ shāo xī gēn diē hùn ér zi lì zhèng gēn niáng hùn]
A playful and humorous expression showing family members mixing roles with parents (the dad hanging out more like a daughter would; son acting more mature like a mother). It depicts non-traditional role reversals within a fun family context.
