Good luck with that
Informal Depends on context
What it really means
Can be sincere, but with a flat tone or raised eyebrows it often means "that will never work, and I will not be helping". The sarcastic version is very common.
Chinese explanation
可以是真心祝福，但语气平淡或挑眉时，常表示"这事成不了，而且别指望我帮忙"。讽刺版用得非常多。
Example conversation
A: I'm going to ask the council to cancel my parking fine.
B: Good luck with that.
A：我打算让市政厅撤销我的停车罚单。
B：那祝你好运喽。
