Loose Lips ,Sink Ships

Today I have for you the origin of
the phrase
"loose lips sink ships." This phrase means to
keep a secret
or else a price will be paid. Here's the origin:

Popularized by US military propaganda during
World War II,
this phrase was meant as a reminder that
classified informa-
tion was never to be discussed with anyone
without proper
clearance and a need to know.

Specifically the phrase means that disclosing a
military
secret to the enemy could result in large loses,
such as the
sinking of an entire ship.
