In the shower this morning I was singing the lyric “Loose lips sink ships” and thought of pirate yore. This stayed with me all day and I had to do a google search. Apparently this slogan was created during WWII.
This phrase was coined as a slogan during WWII as part of the US Office of War Information’s attempt to limit the possibility of people inadvertently giving useful information to enemy spies. The slogan was actually ‘Loose Lips Might Sink Ships. This was one of several similar slogans which all came under the campaigns basic message – ‘Careless Talk Costs Lives‘.
