打肚皮官司

打肚皮官司

Literally means:

don't talk during a lawsuit

Actually means:

have pent-up complanints; rival in trickery by secret scheming

The phrase means having different opinions or complaints pent up in the heart (stomach), or, instead of expressing them, scheming secretly to rival in trickery with the other person or party.

It often shows the speaker's criticism and disapproval of such behavior. Sometimes it is used to advise others not to do this. Derogatory.

指有意见不说，闷在肚子里，或者有了意见不表示出来，暗地里使心计，跟对方斗心眼儿。

多表示说话人对于这种行为的批评、责备，有时用来劝说别人不要这样。具有贬义色彩。
