How does two bit explain greasers to pony boy? What influence does this have on pony boy

The explanation:

"A fair fight isn't rough;' Two-Bit said. "Blades are rough. So are chains and heaters and pool sticks and rumbles. Skin fighting isn't rough. It blows off steam better than anything. There's nothing wrong with throwing a few punches. Socs are rough. They gang up on one or two, or they rumble each other with their social clubs. Us greasers usually stick together, but when we do fight among ourselves, it's a fair fight between two."

Ponyboy is filled with admiration at Two-Bit's ability to vebalize the difference between the two groups.

"I looked at Two-Bit admiringly. He sure put things into words good. Maybe he was still a junior at eighteen and a half, and maybe his sideburns were too long, and maybe he did get boozed up too much, but he sure understood things."
