你美的像你大妈
[nĭ mĕi de xiàng nĭ dà mā]
'Ni Mei De Xiang Ni Dama' directly translates to 'You are beautiful like your grandma/madam', which could be a playful or teasing remark on someone’s appearance - it's somewhat odd or funny in the way it's used, implying an unconventional beauty standard or even sarcastic admiration.
