万丈光茫好菇凉
[wàn zhàng guāng máng hăo gū liáng]
Here, '万丈光茫' means radiance or spotlight. However '好菇凉' could be a misspelling of ‘好姑娘’ (hao2 gu1niang) meaning good girl, or a phonetic internet slang used to describe girls who have unique personality. Taken literally, this could suggest the individual believes they’re like an amazing young lady basking in the limelight.
