贱人別贱
[jiàn rén bié jiàn]
Translates roughly as 'stop acting cheap/dirty.' It appears quite direct and somewhat derogatory, possibly chosen either humorously or in response to someone or a situation that provoked strong emotions. This type of username could express frustration or dissatisfaction with oneself or others. In some cases, choosing a self-deprecating name can be a form of rebellion or irony used to deflect criticism.
