“打肿脸充胖子”，中文歇后语，字面意思是“slap one’s face until it’s swollen in an effort to look imposing”，比喻宁可付出代价而硬充作了不起，为撑面子，做一些自己力不能及的事情（try to satisfy one’s vanity when one cannot really afford to do so）。
- 他真会打肿了脸充胖子！
He’s just making himself look fat by slapping his own face! - 人家都知道我们快要破产了，何必还打肿脸充胖子。
There’s no point in keeping up appearances when everyone knows we’re nearly bankrupt.
