look up any word, like blumpkin:
A flour used for cooking that's made by grinding smokeable parts of the cannabis plant into a fine, powdery dust using a coffee-grinder, blender, or herb grinder. Often confused with THC "crystals", but nearly as potent.

King Gamberro's Recommendation: Check out all that dusty stuff stuck to the sides and bottom of the grinder after you've emptied it. That stuff is extra-potent and great for cooking! Collect it using a fingertip and empty it in with the rest of your cannaflour.
You'll waste a whole lot of potency cooking with weed if it's not ground down to cannaflour first.
