An alcoholic beverage that is cheap but potent and carried in a brown paper bag. The word is somewhat racist, being derived from jigaboo (an offensive racist term for an African-American) and booze (which means liquor).
Tommy bought some Mad Dog 20/20, kept the bottle in a brown paper bag, and drank it all night. We made fun of him for drinking jigabooze.
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
