笨菇凉
[bèn gū liáng]
In casual internet slang in Mandarin, 菇凉 ('girls') is written using characters that create homophonic jokes. This net name combines 笨 ('foolish'/'dumb') + 菇凉, meaning ‘naive girl’. Such a name can either express modesty from the holder herself or a joking endearment by those around her.
