Why is the book the outsiders called the outsiders

This book is titled The Outsiders because the name Outsiders ostensibly refers to the Greasers, social outcasts who band together for a sense of belonging and safety. The name also refers to Socs and Greasers who see beyond their group identity to recognize the humanity in their rivals.
