I'm having a hard time understanding this (idiomatic expression? maybe?) What does it mean, and why is it constructed like that? Why does the verb come first?

I'm going to provide a few sentences I found online.
Boy, am I glad to see you!
They eat cookies for breakfast and boy is it good!
I once thought all women were the same. Boy, was I wrong!
