管我美不美又不你媳妇管我丑不丑又不你爷们
[guăn wŏ mĕi bù mĕi yòu bù nĭ xí fù guăn wŏ chŏu bù chŏu yòu bù nĭ yé men]
A playful and somewhat rebellious statement which roughly means: 'Care if I am beautiful or not, it's not like I'm your girlfriend; care if I'm ugly or not, it's not like you're my man.' It reflects defiance towards societal or personal opinions.
