在牛b的男人也会阳在牛b的女人也会下垂
[zài niú b de nán rén yĕ huì yáng zài niú b de nǚ rén yĕ huì xià chuí]
This phrase is rather crude and sarcastic. In colloquial terms, it means even strong men will experience their moments and powerful women also have their weaknesses, highlighting the universal nature of imperfections.
