你和小三要跳楼我在旁边喊加油
[nĭ hé xiăo sān yào tiào lóu wŏ zài páng biān hăn jiā yóu]
A very harsh phrase that refers to a scenario where the user is sarcastically supporting the protagonist ('加油 means cheer for/good luck') in a destructive relationship situation. This highlights a dark form of schadenfreude and reflects a dysfunctional viewpoint on relationships.
