为自己带盐的人都特么自私
[wéi zì jĭ dài yán de rén dōu tè me zì sī]
The English word 'salt' has many implications. This nickname can be understood as a critique: 'those who add spice to themselves (or emphasize only good qualities when talking about themselves) are selfish bastards'. In other words, self-boasting behavior could lead to being seen as selfish and vain.
