what are two things greasers say they have to be pround of?

1) Their hair......

"It was my pride. It was long and silky, just like Soda's only a little redder. Our hair was tuff - we didn't have to use much grease on it. Our hair labeled us greasers, too - it was our trademark. The one thing we were proud of. Maybe we couldn't have Corvairs or madras shirts, but we could have hair."

2) The fact that they look mean......

"Ponyboy notes that, "We can look meaner than anything when we want to - looking tough comes in handy."
