Oojah-cum-spiff

“[…]the first thing tomorrow, my dear fellow, I must take you round and show you my gardens.” “I shall look forward to it keenly,” said Psmith. “They are, I can readily imagine, distinctly oojah-cum-spiff.”

“All you have to do,” I said, “is to carry on here for a few weeks more, and everything will be oojah-cum-spiff.”

He thought for a long time and said, “You don’t spell it, you just say it.” The word in question was “croos”: it is a word for “lively”, “fit”, “oojah-cum-spiff” – I have no idea whether I have spelt it correctly; it is possibly the first time it has ever been committed to paper.

“It’s done,” Morgan said. “Excellent. Things are looking oojah-cum-spiff.”
