The idiom "living under a rock" means that someone is unaware or uninformed about something that is common knowledge or widely known. It is usually used to describe someone who is out of touch with the world around them or who is not keeping up with current events or trends.
For example, if someone has never heard of a popular TV show or movie, you might say, "Have you been living under a rock?" This means that the person has been so disconnected from popular culture that they have missed out on something that most people are aware of.
Similarly, if someone is not aware of a major news event or political development, you might say, "Are you living under a rock?" This means that the person is not paying attention to what is happening in the world and is therefore uninformed.
Overall, "living under a rock" is a way of expressing surprise or disbelief that someone could be so unaware of something that is widely known or talked about.
