Call comes from Japan’s support culture and expresses support for idols. Now it is more about support and affirmation of people, things and things. Calling is a unified support method. Like a glitter stick that shakes evenly. Usually used in concerts. It is a collective dance of the masses. Calling is a physical job that talks about involvement and respect, especially when used in concerts. If you don't have good physical strength, you won't be able to pass the concert. Of course, pay attention to the title itself and don't get in the way of others. Sometimes when the stick is swung, the person in the front row who accidentally hits it will apologize and then look at each other.
If you are willing to call, supporting idols is a follow-up extension.
