Don't worry I'm confused also...Let's see if I can make sense of this.
Original topic was such that we substitute 'staples' (common goods which price is typically fixed...gasoline is a bit of a outlier) for actual currency.
When I said, "It's usually more a long the lines of, "****, I could get a half-quarter for the price of that CD""
I was referring to MJ, Mary Jane, Pot, Cannabis, Marijuana...a couple of guys said that they hadn't heard to an 1/8th of an ounce referred to as a half quarter before...I mentioned it was a Canadian thing...someone asked if I was from australia (jokingly)...and then you said that if it were australia gas would = petrol (which is indeed accurate).
and now here we are.
