Found this one first;

Grog (Groggy):

Comes from the nickname the British sailors had for their West Indies
Commander, Admiral Vernon, who wore a cloak made of a coarse cloth called
grogham. "Old Grog," as they called him, made his men dilute their daily
pint with water, in hopes of reducing the rum's effects; the men simply
drank the mixture faster, and became groggy.

beer is NOT grog!!!!!!!


The Hell it ain't! Look up the definition of grog and you'll
see something like 'alcohol and water'. What is beer but
alcohol and water with a few hops thrown in for flavor?

S.Simon - a Captain who knows his grog!
