all heart

1. Very considerate and generous. Of course Jenna gave you her last dollar—she's all heart. My son is all heart, always giving up his toys to his friends and classmates. A: "I still volunteer whenever I get the chance." B: "I'm not surprised to hear that, Betsy. You've always been all heart."

2. Of an athlete, especially gritty and courageous, perhaps to make up for talent. Peter may not be a star, but he's all heart and always willing to play against the other teams' best players. Hey, give this kid a look. Sure, he's small, but he's all heart and very solid defensively. I can't believe that guy came back and finished the game after taking a puck to the face. Talk about being all heart!
