跟没事人似的。(Gēn méishìrén shìde.)It’s like nothing to do with somebody; It seems as if nothing has happened.

Explanation

这个短语的意思是好像和自己没关系似的或像什么都没发生一样，常指某人和某件事有关系，但是却故意不理会，装作和这件事没有关系。主要在两种情况下使用。第一，有不好的事情发生时，装作没发生过似的；第二，对于做错的事情或者需要负责任的事情，不理会，不道歉，也不承担责任。
The phrase “跟没事人似的（Gēn méishìrén shìde.）” means it’s nothing to do with somebody or it seems as if nothing has happened. It is mainly used in two circumstances. Firstly, one pretends that nothing bad has happened. Secondly, it is used to describe a person, who neglects and refuses to admit his or her faults or does not take responsibilities.
