Describe the gang know as the greasers

The Greasers define themselves by toughness and invincibility; they'll take part in rivalry and violence, but NOT ever will they hurt children. The greasers can't afford things, but they will steal things. They distinguish themselves by the way they wear their hair, the "grease," and by allowing it to grow out. This is their mark as a group. Even the Socs know this, which is proven by the fact that they threaten to cut Ponyboy's hair; for them to cut his hair would be to take away his identity. Ponyboy's gang is more like a family.
