originally used to describe
weed on grateful dead tour that was not for sale. you might smoke with some one on the parking lot of a Grateful Dead show, fellow
head maybe, and loved the taste you just had dance across your palate and ask to buy some, only to be told nah' bro these are just headies. later it was used to describe a level of
dank and parking lot sellers would describe their
bud as headies. of course this is all realitive compared to what one has tried and has access too.
