2逼青年欢乐多精神病人思维广
[2 bī qīng nián huān lè duō jīng shén bìng rén sī wéi guăng]
This nickname uses internet slang humorously to refer to oneself (as a 'rascal' or 'foolish') who has wide-ranging thoughts. The mention of 'mental patient' is not serious but rather an exaggeration used sarcastically by some young Chinese netizens, implying someone being imaginative or having a unique perspective on life.
