Refers to the moment in which you realize that a specific alcoholic beverage, most likely beer, is insanely pleasing thus you must continue to drink. However Beertastic can be used simply to describe a moment in which you must drink, have drank, or when you simply want to display pleasure with a certain action non-alcoholic related!
