whats the difference

Can anyone tell me what the difference is between headies, mids, and dank. Is there different kinds of each? How do I know which one is which. Whenever I buy I always hear about these three and i am confused as hell about what they are. Please HELP. THanks

Regs/shwag is low quality herb, mids is better quality herb, beasters is great quality herb, headies is the best quality herb. Dank just means really fuckin good and can describe anything, not just green.
