An acronym for a drink that is popular in Dirty South hip hop culture. MNJ stands for Mad Nigga Juice. The original recipe is a mixture of malt liquor and Dr. Pepper in a big-gulp style cup that has been filled with ice.
Did you see Dean Thomas at the party last night? He was so busted he was drinking hella MNJs!
