"Giddy" is often a good thing. Most of the time, at least. And in this case as well. It's an accomplishment--or as the French say: "accomplissement"--something to take pride in.
Giddy-pride. (Sounds too much like "gay pride.") Prideful giddiness. (Eh.)
Giddy is a terrible word phonetically. It's not manly at all.
