每个学霸的旁都有一个学渣
[mĕi gè xué bà de páng dōu yŏu yī gè xué zhā]
This name reflects a humorous observation that in school, there's usually a top student (scholar) who studies hard, and right next to them is always someone (a slacker) who struggles with studies or does not try at all. It’s a relatable and funny comment on the common dynamics between diligent and less diligent students.
