First-world problem refers to a trivial frustration¹ 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，和发展中国家所面临的严重问题形成鲜明对比。

 

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.

明迪很为派对上穿什么衣服而苦恼，连饭都吃不下去了，而她的丈夫却不以为意，认为这是个无足轻重的“第一世界问题”。
