A person who is extremely well-versed in all things related to
Marijuana. Usually a dealer or grower himself, a Kushmaster knows how to roll the best joints, pack the most righteous bowls, and he always has a lighter. Kushmasters usually
smoke a quad a
day or more, and they will be down to bake anytime, anywhere.
Person: Hey Kushmaster Dave, how much for an eighth?
Kushmaster Dave: Sorry man, I only
deal in pounds. But have some of this Skywalker OG, its
dank as hell (passes J).
