待我强大前任我毁你天下
[dài wŏ qiáng dà qián rèn wŏ huĭ nĭ tiān xià]
A fierce expression that means 'When I become powerful, O ex-partner, I shall devastate your world!' Perhaps a declaration made following the ending of a bad relationship where the user vows retribution on an adversary. The tone can be sarcastic as well, depending on personal context.
