Watered-down pussers rum consisting of half a gill with equal part of water, issued to all seamen over twenty. (CPOs and POs were issued with neat rum) From the British Admiral Vernon who, in 1740, ordered the mens ration of rum to be watered down. He was called Old Grogram because he often wore a grogram coat), and the watered rum came to be called grog. Often used (illegally) as currency in exchange for favours in quantities prescribed as sippers and gulpers. Additional issues of grog were made on the command splice the mainbrace for celebrations or as a reward for performing especially onerous duties. The RN discontinued the practice of issuing rum in 1970. A sailor might repay a colleague for a favour by giving him part or all of his grog ration, ranging from sippers (a small amount) via gulpers (a larger quantity) to grounders (the entire tot).
