Thanks, newintown, I was going to point that out. It's also clear when you see it performed that when the entire cast sings the finale, they are sort of reminding the Chaperone what the right word is. I can't really describe what exactly they do to convey this. When they get to that word, everyone looks at the Chaperone and pointedly sings, "Tumble!" and she makes a gesture like, "Oh, yeah, that's it!"
"Agee" is pronounced with a J sound and yes, it means "to one side," so the Major General says "sat agee" to mean "to sit on a horse." Why the Major General rides sidesaddle, I have no idea, but I have always found it extremely impressive that all those words are actual words.
I always enjoy the gibberish in WICKED because it fits in with the world. I appreciate when composers write their songs to match the voice of the character, and these characters use made up words like this all throughout the dialogue, so why not in songs? That wasn't Schwartz being lazy or weird, he was writing for his characters and their world.
