Boomshine is the name of an highly flammable and volatile liquor in the Grand Theft Auto series. It featured in Grand Theft Auto: Vice City, Grand Theft Auto: Vice City Stories, and on Grand Theft Auto III's Liberty Tree article. According to Phil Cassidy, Boomshine's vapor itself are apparently enough to intoxicate a person. It is a parody of the moonshine, a liquor that is known for its highly volatile alcohol.
