Loose Lips Might 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. 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. Interestly, everyone remembers the quote differently that it is actually printed - the poster actually reads, "Loose Lips MIGHT Sink Ships."
