Idiom: Loose lips sink ships
What does 'Loose lips sink ships' mean?
Loose lips sink ships comes from World War I and/or WWII, when sailors on leave from their ships might talk about what ship they sailed on or where it had come from, or where it was going. If they talked too much (had 'loose lips') they might accidentally provide the enemy with anecdotal information that might later cause their ship to be tracked, and bombed and sunk, hence 'Loose lips sink ships.' Later, it came to mean any excessive talk might sabotage a project.
