A diluted mixture of rum that originally included sugar and citrus juice. Slang associated with it is "Tanky", the server of it. Served in a "can" no matter what the vessel was. It was discussed in its water to rum ratio by compass points and in numbers, north being pure rum and east being water. The authentic recipe is so short and excellent, I'll give it to you:
Grog 1:4/four-water
half cup rum
pint water
1/8 cup sugar
" " lime or lemon
"Five-water grog? Give me some more northing!" (north = more alcohol)
"Oi! Tanky, me grog can!"
