打的过流氓骂的过小三
[dă de guò liú máng mà de guò xiăo sān]
'Tough enough to fight off thugs and strong-mouthed enough to scold homewreckers'. This implies someone who is fierce and not afraid to stand up for themselves. In modern internet slang, it could reflect someone's assertiveness or self-protection abilities against bad behavior or interference in one's personal life.
