贱人跳楼我在楼下喊加油
[jiàn rén tiào lóu wŏ zài lóu xià hăn jiā yóu]
This translates as 'The scumbag jumps from a building, and I shout encouragements from down below.' This internet slang carries dark sarcasm, often used as a dramatic or exaggerated response to express disliking or animosity towards someone.
