姐霸气关你屁事
[jiĕ bà qì guān nĭ pì shì]
This nickname expresses a rather rude and indifferent attitude, suggesting that the person does not care about others' opinions or advice. The word '姐' (jiejie) means sister or elder sister in Chinese, sometimes used as a casual way to refer to oneself by women. '关你屁事' is very colloquial and offensive language equivalent to saying 'None of your business' but in an impolite manner.
