学霸学霸不学也罢学渣学渣不学人渣
[xué bà xué bà bù xué yĕ bà xué zhā xué zhā bù xué rén zhā]
This nickname combines humor with sarcasm, playing on the stereotype of model students ('Xueba') and underachievers ('Xuezha'). It suggests that sometimes even hardworking students might admit that not studying could be better for the underachievers because they have no hope to do well in study anyway. This phrase expresses self-deprecating cynicism or a satirical comment on academic pressure.
