Another idea to describe the greasers from The Outsiders?

I am writing an essay and i describe the greasers and their differences from the Socs. I said that they had greasy hair, leather jackets, and i dont know what a third idea should be. For the socs i put that they have madras, money, and mustangs (as an example). I need help finding a third idea for the greasers description!! REAL ANSWERS! thank you!
