逞强一时逞强不了一世
[chĕng qiáng yī shí chĕng qiáng bù le yī shì]
The meaning of the nickname can be translated into English as 'Be Stubborn for a Moment, Cannot Be Stubborn Forever.' This phrase indicates that sometimes, while you might get away with putting on a brave front in short term, in a longer period you have no choice but to acknowledge the truth or show vulnerability.
