Running rigging is that which is easily adjustable, such a the main sheet, used to adjust the main sail, or the rigging on a ships crane which raises and lowers cargo. 	
Rope	There is some confusion over the term rope. Rope is considered to be the bulk source of line. While the rope is stored waiting for use it is properly termed "rope." Once it has been taken from storage and put to use it should then be called line.

shrouds	transverse wires or ropes that support the mast laterally. 	
slush	Grease obtained from the meat boiled in the coppers and used as a lubricant and for slushing the spars after scraping.	
son of a Gun	Many people use this, with no inkling of the original meaning. Going back to the days of sail, when a woman gave birth on (or under) the gun deck, the child was said to be a son of a gun. Usually the father's name was not known, hence calling some one a son of a gun is short of calling him a bastard.
