小三同情你连破鞋都要
[xiăo sān tóng qíng nĭ lián pò xié dōu yào]
'Little Third, even pitiful as an old shoe,' expresses contempt for a situation involving being or becoming the third party in a relationship. It highlights a bitter irony—feeling sorry for the person who is viewed negatively ('third party' often has negative connotations in Chinese culture) yet still finding oneself in that position.
