你是我爷们拉起你裤子你是我娘们穿好你衣服
[nĭ shì wŏ yé men lā qĭ nĭ kù zi nĭ shì wŏ niáng men chuān hăo nĭ yī fú]
The name uses playful and colloquial language to say 'if you are my buddy pull your pants up, if you are my gal dress up properly.' It’s a humorous, casual, and unconventional nickname, maybe representing the user’s lighthearted or nonchalant personality, and their willingness to cross gender barriers playfully.
