小三要跳楼我来喊加油
[xiăo sān yào tiào lóu wŏ lái hăn jiā yóu]
Translating to 'I'll cheer on while the homewrecker jumps off the building'. This carries a sarcastic and bitter tone, expressing dissatisfaction towards a person (third party) who might have broken up a relationship, emphasizing a vindictive or harsh perspective toward that person's misfortune.
