小三玩的始终都是剩货
[xiăo sān wán de shĭ zhōng dōu shì shèng huò]
'The Third Party Always Ends Up with Leftovers' criticizes the affair between a mistress ('xiaosan', commonly used in Chinese culture to describe third party who ruins others' marriage) and an unmarried individual where both might end up having nobody after all when it breaks out, expressing cynical views on extramarital relationships. Such a term may contain negative stereotypes.
