菇凉我天生傲骨非良人
[gū liáng wŏ tiān shēng ào gú fēi liáng rén]
I'm not good material, I'm born proud like 'Gu Liang'. Here, Gu Liang can mean mushroom girls but also be interpreted as a metaphor for someone unique. In fact, this nickname indicates the owner believes themselves to have noble character (born proud) and unconventional personality.
