我和你疯了累了散了拜拜了你和她滚吧吻吧爱吧去死
[wŏ hé nĭ fēng le lĕi le sàn le bài bài le nĭ hé tā gŭn ba wĕn ba ài ba qù sĭ]
This translates roughly as: I'm done, exhausted, we're finished, goodbye - now you can fool around, love her and die which expresses anger and bitterness after an ending relationship. An outpouring of all kinds of mixed emotions like fatigue, despair, sarcasm, hate and letting go while mocking or showing indifference to whatever happens next.
