卖萌比装逼更可耻
[mài méng bĭ zhuāng bī gèng kĕ chĭ]
Roughly means 'acting cute can be just as obnoxious or embarrassing as trying too hard'. It plays into a social critique, humorously calling attention to behaviors perceived as annoying whether from seeking pity via cuteness or arrogance and pretentiousness.
