萌以饭用
[méng yĭ fàn yòng]
This user name '萌以饭用' combines two elements. The first, '萌' (méng) is widely used to describe something adorable or cute. The second part '以饭用' literally means 'used for meals', suggesting the owner of this nickname might like to express their cuteness even during mealtimes, or perhaps they're indicating their love for food.
