A: I was so angry that John quarreled with me the whole evening over such a small thing. I had to work overtime and was late for the show. We missed the first act and he complained about it, bringing up some old grudges too.

B: Just zip it. I’m tired of listening to you complain.

Note: This saying means “Stop talking immediately.” It originates from the exaggeration of closing a topic by zipping the mouth of the person talking, just like closing a zipper. It is used more as a slang term and one would not hear it in a formal conversation. It’s rude and angry way of telling people to stop talking, as angry parents would tell their children.
