生活英语|first-world problem 第一世界问题

First-world problem refers to a trivial frustration^{1 or petty concern, particularly one that contrasts sharply with serious problems such as those faced by developing nations.}

第一世界问题指的是微不足道的挫折或琐碎的烦心事，和进步中国家所面临的紧急问题形成鲜明对比。

Example:

Mindy feels so worried about her party dress that she has no appetite to eat, while her husband brushes it aside as a first-world problem.

明迪非常为派对上穿什么衣服而烦恼，连饭都吃不下去了，而她的老公却不以为意，觉得这是个无足轻重的第一世界问题。
