笨蛋跟着我傻瓜跟着你
[bèn dàn gēn zhe wŏ shă guā gēn zhe nĭ]
This nickname suggests an endearing and slightly self-deprecating tone, expressing a sense of humor in the interaction between friends, indicating that even if one is foolish or naive ('idiot' and 'fool') they are still following or accompanying each other.
