The theme of belonging in The Outsiders comes about in the greaser's family-like relationship. They're not your typical friend group. All of them watch out for one another, making sure no one gets injured or is upset. In a way they have their own support system. This shows in Johnny's everyday life. He has bad parents, but his other family, the gang, manages to provide some balance in his not-so-good life. The title is not only saying that they're not like the rich side of town. It's explaining how those who aren't as fortunate are more likely to stick together, leaning on each other's shoulders. And when it comes to being a greaser, that bond with others certainly comes in handy.
