The expression "mill around" means to move around in a group or crowd without any particular purpose or direction. This phrase is often used to describe a group of people who are waiting for something, such as a concert or a bus, and are passing the time by walking or standing around. It can also refer to a group of people who are unsure of what to do or are waiting for instructions. For example, when waiting in line to get into a movie, people might mill around the lobby until the doors open.
