小三用骚闯天下
[xiăo sān yòng sāo chuăng tiān xià]
'The mistress uses charm (or provocative allure) to take on the world' can imply using one's attractiveness to achieve success or power, potentially in an unconventional or unethical manner. It could symbolize audacity and defiance, but should be noted as carrying negative connotations and controversial content.
