What does Ponyboy call Cherry after she delivers the news about the rumble?

Ponyboy calls Cherry a traitor after she gives him information about the rumble.

Towards the end of Chapter 8, Cherry Valance runs into Ponyboy and Two-Bit, and she tells them that the Socs are willing to play by the rules in the upcoming rumble. Cherry says that Randy told her that they would fight fair and not bring weapons. Cherry then tells Pony that Randy isn't going to show up for the fight and politely asks how Johnny is doing. Pony tells Cherry that Johnny isn't doing well and asks if she'll visit him. When Cherry says that she won't visit Johnny, Ponyboy gets upset and asks why not. Cherry tries to explain that she couldn't look at the person who killed her boyfriend because she still feels strongly about Bob. Ponyboy understands Cherry's reasoning but is still bitter about the situation. He knows that it wasn't Johnny's fault that Bob got drunk and tried to start a fight. Ponyboy then tells Cherry that he wouldn't want her to see Johnny anyway. He says, "You're a traitor to your own kind and not loyal to us" (Hinton 110). Pony can't help himself and voices is displeasure at Cherry and her easy-going affluent lifestyle. After making several negative comments, Ponyboy realizes that he was wrong and remembers that Cherry's struggles are similar to his. He then smiles at her and asks her if she can see the sunset good from the West Side. Cherry responds by saying, "Real good" (Hinton 110).
