thinking one's shit doesn't stink

Smug about oneself

Thinking one's shit doesn't stink describes smug self-regard—believing oneself superior to ordinary human failings or immune to criticism.

The image is of someone so convinced of their own excellence that even their bodily waste couldn't possibly offend.

Usually applied critically: He acts like his shit doesn't stink, but he makes the same mistakes as everyone else.
