A dimebag has always, at least where i'm from, been 1 gram and 1 joint weighs to 0.5 grams. Anything more then a dimebag will always vary on who your dealing with.
I noticed nobody mentioned Krippy. I'm from Puerto Rico so when we get some Krippy in our area you know we get happy. Krippy is essentially the best of the best. Dark green bud with red/orange/yellowish vines all over it, or as they call it here, Chronic. Sinsemilla (sin seh mee ja) is common, but even bush can be Sinse over there.
Bush or crappy weed is "Fangola" the name is basically an insult to whoever has the weed, making it seem like if it was grown in a swamp or in mud (fango)
I can't think of anything else, but we usually don't have extremely good weed over there. Krippy/Chronic is rare and well appreciated when we do get it. I'm in NY right now and thinking about smuggling some weed somehow when I move back in a couple months.
