惺惺作态自觉滚蛋
[xīng xīng zuò tài zì jué gŭn dàn]
In Chinese, '惺惺作态' indicates a pretended pose for selfishness or ulterior purpose, while '自觉滚蛋' suggests telling someone to go away by himself. As a whole, this is more likely to represent a rebellious personality, expressing a refusal towards certain behavior, indicating a desire not to be bothered.
