I always refer to top notch bud as "Kron", but around here they call it "Dro". Everywhere you go there is diferent slang names for top quality. I think in High Times magazine they refer to top quality as "kind". I think its short for "the kind that killed Elvis".
If it's Dank it's good. People use it to describe very strong smelly potent stuff or as the cop said " this is the most pungent dope I ever seen" must have smelled the bag 100 times lol
