At some mess nights, violators of the mess are obliged to publicly drink from a grog bowl in front of the mess attendees. The grog is sometimes contained in a toilet bowl, consisting of various alcoholic beverages mixed together. As a more disgusting effect, the grog may also contain floating solids, such as meatballs, raw oysters, or Tootsie Rolls. The tradition of drinking grog originated with the British Navy. Grog consisted of the regulation rum ration diluted with water to discourage binge drinking. In modern times, grog comes in two varieties: alcoholic and non-alcoholic, the latter of which may contain anything that will make it less appealing to the taste, including hot sauce. For additional effect, the drinker may be required to drink from a boot.
