小三落伍闺蜜上档次了
[xiăo sān luò wŭ guī mì shàng dàng cì le]
Literally means 'the mistress concept has become outdated, now friends have more status.' The term 'mistress' here ('xiao san') refers to a person engaging in a romantic affair outside marriage, while 'close female friends' have taken precedence or gained recognition. This reflects shifting cultural attitudes favoring friendship over extramarital affairs.
