何必喊破喉咙装疯卖傻强逞
[hé bì hăn pò hóu lóng zhuāng fēng mài shă qiáng chĕng]
Translates to 'Why shout until hoarse pretending to be crazy, silly or strong?,' questioning the point of such strenuous, perhaps self-destructive efforts of false bravado, or putting up a facade when genuine communication would be more effective and honest.
