A knock is someone who is a fiend for drugs of any kind. There can be weed
knocks, coke knocks, pill knocks, etc... Also refers to when someone exhibits "knockish" behavior, i.e.
fiending for drugs or just acting square. (see square) The word knock is derived from the "knock" of a fiend
knocking on the door looking for drugs.
I was left with
the decision of whether to bust some
knocks and make that money or just
kick it with these females.
