A word for marijuana. Developed in the late '90's by a couple of guys from San Diego. The word started as "chronic" and was changed to "bronic" because of some rap influence. The word then changed to "brizzy" because Snoop Dog was huge then (for shizzle my nizzle-type stuff). The word was then shortened to "briz" or "the briz". Then, in an inspirational moment of intoxication, the word became "briznu" because it was fun to say. Other forms such as "griznu", "shiznu", and "the grizz" are acceptable.
Pass me the briznu, I want to get high.
This shiznu is blowing my mind
