皇冠不许掉贱人不许笑
[huáng guān bù xŭ diào jiàn rén bù xŭ xiào]
This internet name is a mixture of arrogance and sarcasm. 'Crown must not fall' expresses the idea that one is noble or high status, and 'bitch cannot laugh' shows a hostile attitude towards others, usually implying self-protection by setting barriers against outsiders.
