Cup of Joe Navy lore: Josephus Daniels (18 May 1862-15 January 1948) was appointed Secretary of the Navy by President Woodrow Wilson in 1913. Among his reforms of the Navy were inaugurating the practice of making 100 Sailors from the Fleet eligible for entrance into the Naval Academy, the introduction of women into the service, and the abolishment of the officers wine mess. From that time on, the strongest drink aboard Navy ships could only be coffee and over the years, a cup of coffee became known as a cup of Joe.Cut and RunMost often thought to mean the cutting of an anchor line in an effort to make a quick getaway.

Sailors used the term to refer to throwing something overboard and it has come to mean getting rid of something.Deliver a BroadsideA broadside was the simultaneous firing of the guns and/or canons on one side of a war ship. Quite a blow, as can be imagined. Today it means much the same type of all-out attack, though done (usually) with words.Devil to PayOriginally, this expression described one of the unpleasant tasks aboard a wooden ship. The devil was the ships longest seam in the hull. Caulking was done with pay or pitch (a kind of tar). The task of paying the devil (caulking the longest seam) by squatting in the bilges was
