In the UK and Canada, a rather cutesy and somewhat outdated was of saying 'fine', 'a-okay', or 'hunky-dory'. All's ticky-boo on the Western front.
It first appeared in the 1920s or 30s, possibly derived from the Hindi phrase tikai babu, meaning "it’s all right, sir". I can't help but think that it may be derived from Gilbert and Sullivan's The Mikado (1885), which was set in Titipu and had Nanki-poo as the main character. This being a Gilbert and Sullivan opera, everything worked out all ticky-boo in the end.
Also spelled tiggerty-boo; sometimes modified into 'ticky-poo', usually by accident.
