笨皇后笑死朕
[bèn huáng hòu xiào sĭ zhèn]
The literal translation would be something like 'the clumsy queen made me die laughing'. In Chinese historical context, '朕' (zhèn) was used as the self-reference for emperors in ancient China. So this nickname conveys playfulness and humor by imagining someone being a very tolerant emperor who gets entertained even when a queen acts foolishly.
