烂好人滥好人

This nickname, which is somewhat of a self-mockery expression, literally translates to a 'rotten good person'. The Chinese term can describe a situation or person who appears to be very good-hearted but often ends up over-burdening oneself with helping others, sometimes leading to unfavorable outcomes. It also could suggest an honest and forgiving attitude, repeatedly tolerating some unreasonable behaviors while knowing that those are 'bad'. Here the redundancy might express one's exasperated feelings on their tendency.
