小三跳楼我喊加油
[xiăo sān tiào lóu wŏ hăn jiā yóu]
In Chinese social terms, 'xiaosan' means a third-party person who inserts themselves into a stable relationship or marriage; it is usually negative in society. The entire phrase conveys mockery or sarcasm towards the chaos that may be involved with this kind of affair in real life. '加油' typically means cheering someone on or giving support, which makes the sentence sarcastic and somewhat dark humor.
