Being fined for the use of foole knave or any other contumelius or slanderus worde

From That's what I call a dining hall by Texan99.

College Hall in Westminster Abbey, built in the 1370s, is said to be the longest continuously used dining hall in London. According to what is now usually called a "doubtful tradition," the long chestnut tables were built from wood salvaged from the wreck of the Spanish Armada. Students at the Westminster School still take their meals there, presumably observing a standard of behavior that would forbid leaving their chewing gum on the underside of the tables. As early as the 16th century, diners aged 18 or more were fined a shilling if they called their companions "foole knave or any other contumelius or slanderus worde."

How delightfully primal. Convert your enemy's warships into the tables from which you dine. Signaling, old and new.
