小三要跳楼我在楼下喊加油
[xiăo sān yào tiào lóu wŏ zài lóu xià hăn jiā yóu]
In Chinese, '小三' means the 'third party', referring to someone in a cheating relationship. The phrase 'I’m cheering her on while standing under the building where she threatens to jump' expresses dark sarcasm regarding a very serious and sensitive situation, indicating disapproval of infidelity or social phenomena around affairs.
