萌面怪瘦檬面抄人
[méng miàn guài shòu méng miàn chāo rén]
Combining cute, eccentric, and sarcastic elements, this might loosely translate as 'Copycatter with Cute Face but Thin Sour Face'. Perhaps indicating someone who appears innocent and endearing yet often mimics others while having a sarcastic or moody side. The term could playfully mock those whose online persona differs greatly from their real personality or actions.
