A hot dog shouts "yee-ha!" while doing something stupid that he knows that he isn't supposed to do, but think will make him look cool, or show he's better than all the other pilots. Most pilots are naturally this sort of person, but they either learn military discipline... or they don't.

A cabbage just sits there while they crash, trying to remember what to do.

This guy was perhaps both. He was attempting an advanced maneuver he had never practiced, and also didn't press all the buttons required for a carrier landing. He also didn't notice they were waving him off.
