What does "Way to be strong,man!" mean in the context?

Ross: Okay! Okay! But if she doesn’t call, it is definitely over! No, wait. Wait. Unless, eventually, I call her, y’know just to she what’s going on, and, and she says she’ll call me back, but then she doesn’t. Then it’s over. (Joey holds his fist up, and Chandler gives him two thumbs up.) Joey: Way to be strong, man!
