学霸修练中学渣养成中
[xué bà xiū liàn zhōng xué zhā yăng chéng zhōng]
Translating to 'In the process of being trained as a scholar and becoming an academic underachiever,' it playfully implies that the user used to be diligent in studying but now may be shifting towards enjoying leisure activities or is having fun at self-deprecating humor about not meeting academic expectations.
