Is anyone familiar with, or know the origin of, the use of "guy" as an interjection at the beginning of a sentence, as a substitute for "gosh!" or "golly!" (or "God"?) ?
"Guy, Holl, that's the most heartrending story I ever heard."
(This includes closed-captioning which reproduces the phrase exactly as I have given it here.)
"Well guy, grandpa, I got a job."
"Guy, Chief, that legend's 200 years old!"
I had never encountered this usage before, so I consulted a half-dozen standard dictionaries of the English language; two slang dictionaries (including the most recent edition of Partridge); two books on word origins; and two books specifically on interjections.
These examples are from between 1965–1971; to me, this implies some sort of period slang, which may only have had a brief vogue.
The fact that major production companies were involved in making the material suggests that the writers employed language that they felt was common enough that it would be recognized by most of their intended audience — which in all cases consisted of native English-speaking Americans.
That neither I, nor several other Americans I've asked can remember ever encountering this particular usage before suggests that the popularity of this usage was short-lived, and possibly also regional.
