2. A chiefly Canadian term of familiar or affectionate address to a girl or young woman; apparently derived from a Mexican Spanish phrase composed of the word chica(girl) and an adjectival starting with the preposition "de"; the original phrase was forgotten because Spanish is not commonly spoken in Canada, and the spelling was conformed to that of the bird. Only known and used in certain areas.
2. Hey there, chickadee! You're back from Chilliwack, eh?
