笨蛋牵着我傻瓜说爱我
[bèn dàn qiān zhe wŏ shă guā shuō ài wŏ]
Translating into English it's like 'A fool is holding my hand while a dummy says he/she loves me'. Such a nickname could express the user's self-disparagement or amusement in describing a relationship that involves themselves in a less flattering light.
