傻比不萌逗比不帅
[shă bĭ bù méng dòu bĭ bù shuài]
This username plays on silly-sounding Chinese terms. '傻比不萌' implies 'not cute despite being foolish,' and '逗比不帅' means 'not handsome despite acting silly.' It's often used by someone who admits they are not conventionally attractive or cool, but is comfortable with their quirks.
