First of all, I'd like to focus on the slang phrase "bosco absoluto" and "bosky".

Here's a Mudcat post that I found:

Bosko absoluto (No idea what 'bosko' means, but dates back to WWI & beyond; possibly Army slang, rather than general)...

Here's what I've found so far:

[Page 149, line 14] bosko-absoluto (bosky-absolute). A neat composite word. "Bosky" is a dialect word of 1730 meaning "tipsy" and "absolute" is a natural superlative. Hence very drunk indeed.

and


Bosco/Bosko absoluto - Dead drunk. Mock Latin.
Bosky - Almost drunk, tipsy. Possibly from "bosk," a thicket, and thus alluding to the obscurity of thickly wooded country. Dates from circa 1730; still in British army slang in the 1920s.

Is this mystery solved?

Are these words British English? And if so are the still used in Britain? And does anyone who lives outside of Great Britain heard "bosco absoluto" and/or "bosky" being used?

Inquiring minds want to know [or at least my inquiring mind wants to know].
