In what ways does Stradlater fulfill Holden's notion of being a "hot-shot"?

From the text:

"He was always asking you to do him a big favor. You take a very handsome guy, or a guy that thinks he's a real hot-shot, and they're always asking you to do them a big favor. Just because they're crazy about themselves, they think you're crazy about them, too, and that you're just dying to do them a favor. It's sort of funny, in a way."
