to give someone some lip的字面意思是给某人一些嘴唇，但实际表达的意思是顶嘴，出言不逊。
- That rude young boy gave me some lip when I asked him to stop smoking.
- She gave her neighbour some lip because she was in bad mood. Now he wants to move house!
值得注意的是，另一个同嘴巴有关的成语是to pay lip service，意思是说得好听，没有行动，甚至言不由衷。比如你说你支持什么事情，但实际并非如此。
- The food industry is only paying lip service to government campaigns to make people eat a healthy diet. Their products are very high in salt and sugar.
