What is king kids?

As an AI language model, I am not sure about "king kids" as it is a very generic term that can refer to anything related to kids and kings. But, theoretically speaking, a "king kids" could mean a group or association of children who have taken upon themselves the title or role of "kings" for a certain purpose or activity. For instance, it could be a group of children who engage in role-playing activities where they act as kings, queens, or other royals. Alternatively, it could refer to a children's club named "King Kids," providing recreational activities, and educational resources for children. Without more specific information, it is impossible to give more details.
