"Mad Dog Read" 'ere, in pedant mode.

"Grog" is the Royal Navy's term for pure rum diluted with four parts water, and issued by pursers aboard. The term "Grog" itself is derived from Admiral Vernon, a stern disciplinarian who was known as "Old Grogram" by association with this stiff, unbending material.

(Obviously, Vernon deprecated having seamen lying about half dead from privately acquired rum, usually pure firewater, and so made it an official, strictly controlled ration issue).

Where was I ? Oh, I remember. Essentially, no self-respecting pirate would admit to drinking Grog (unless they had been discharged from, or deserted from, the Royal Navy).

End pedant mode. Is such sea-lawyering punishable by marooning, keel-hauling, being triced up to the yardarm, or just having me vittles stapped ?
