Nice one! – If someone is impressed by what you've done, they could use this expression. It's similar to “good job” in American English. It can also be used sarcastically.

如果一个人对你所做的事情印象深刻，就可以使用这个表达。它跟美式英语里的good job差不多，也可以用于带有讽刺意味的夸奖。

例句：

-I managed to get two tickets for the One Direction concert at the O2 arena.

我设法弄到了两张One Direction在伦敦O2体育馆的演唱会门票。

-Nice one, mate!

干得漂亮，伙计！
