A person that loves to drink bourbon, and will talk shit at the drop of the hat when intoxicated. Whether its mixed with water, soda, or on the rocks this person will take it. They know that there is no better drunk quite like a bourbon drunk. A true Bourbonator has learned to appreciate the finer bourbons (Makers Mark, Bookers, Knob Creek, Blantons) and will not drink the shitty, cheap well bourbon at a bar.
That dude has been killing the bourbon all night long he's a fucking bourbonator....I wouldn't fuck with him.
