放不下那你去死好了
[fàng bù xià nèi nĭ qù sĭ hăo le]
This is a harsh nickname, often used sarcastically when the speaker feels that someone clings too much to certain things, and their impatience has reached an extreme point, meaning 'if you can't let it go, you might as well die'. It's an exaggerated expression reflecting emotional fluctuations in some people's minds.
