(deyim) Davy Jones’s Locker is an idiom for the bottom of the sea — the resting place of drowned sailors. It is used as a euphemism for death at sea (to be sent to Davy Jones' Locker). Davy Jones is a nickname for what would be the devil of the seas. The origins of the name are unclear, and many theories have been put forth, including incompetent sailors, a pub owner who kidnapped sailors, or that Davy Jones is another name for the devil – as in, “Devil Jonah”. This nautical superstition was popularized in the 1800s
