作业和网名私奔勒老湿
[zuò yè hé wăng míng sī bēn lè lăo shī]
Translated as 'the homework ran away with the nickname (to elope), Mr. Laoshi'. '老湿' here humorously refers to teachers due to its homophonous pronunciation of the word for wet, implying teachers are always busy getting their work done but having fun setting funny online names at the same time.
