Puna butter is a colloquialism used by native Hawaiian's to reference cannabis. Though generally "a high quality marijuana bud", as described above, the origination of the term, to my knowledge, is specific
to the Hawaiian Islands. In the definition and context listed on this web site, "Puna Butter" would have the same meaning as "KGB" or "Chronic"; a superlative
or extremely potent variant
of marijuana, when in fact "Puna butter" is more in line with more "common" terms
like "weed", "grass", "pot" and "reefer", a regional reference for marijuana w/o regards to its potency.
