A gang leader is a person who is in charge of a group of people, often involved in criminal activities. The term 'gang leader' can be broken down into three words: BOSS (4 letters), KOOL (4 letters), and OUR (3 letters). BOSS stands for the person in charge, KOOL stands for someone who is cool and respected, and OUR stands for belonging to the group. Together, these words describe a gang leader as someone who is in charge, respected, and part of the group.
