“Loose lips sink ships”
“Loose lips sink ships” is a World War II saying meaning that one shouldn’t talk too much (“loose lips”), or the enemy might overhear the conversation and use the information to attack (“sink ships”). A poster, “Loose Lips Might Sink Ships,” was created Seagram Distillers Corporation by the designer Seymour R. Goff (also known by the pseudonym “Ess-ar-gee” or Essargee) and has been cited in print since at least February 4, 1942. “Loose lips sink ships” (without the word “might”) has been cited in print since at least March 11, 1942.
The WWII saying is still known and sometimes used in the military, in intelligence circles, in politics, in business, and elsewhere.
Wikipedia: Loose lips sink ships
Loose lips sink ships is an American English idiom meaning “beware of unguarded talk”.
The phrase originated on propaganda posters during World War II. The phrase was created by the War Advertising Council and used on posters by the United States Office of War Information.
The most famous poster that helped popularize the phrase was created for the Seagram Distillers Corporation by the designer Seymour R. Goff (also known by the pseudonym “Ess-ar-gee” or Essargee). This type of poster was part of a general campaign of American propaganda during World War II to advise servicemen and other citizens to avoid careless talk concerning secure information that might be of use to the enemy. The British equivalent used variations on the phrase “Keep mum,” while in neutral Sweden the State Information Board promoted the wordplay “en svensk tiger.”
