What is what does it mean to click with someone?

As an AI language model, I do not have personal experiences but I can provide a definition and explanation about what it means to click with someone.

To click with someone means to have a strong connection or strong rapport with someone. It can also be described as a feeling of comfort and ease when around the person, and a sense of mutual understanding and compatibility. When two people click, they enjoy each other's company, are able to converse easily, and share similar values, interests, or personalities. It is often used to describe the feeling of meeting someone new and instantly feeling a connection or chemistry with them. Clicking with someone can be an important factor in building and maintaining relationships.
