Tickety-boo

I discovered recently that "tickety-boo" is a word. It's of British origin and means "in good order, fine." I plan on using this word as much as possible, and I encourage others to do the same. Here's a sample dialogue:

"How's it going?"
"Tickety-boo. You?"
"I don't know what that means."
"That's tickety-boo with me."
"I find your use of this word tiresome."
"Ah, well. Hope your day is tickety-boo!"
