In maritime lingo, flotsam is wreckage or cargo that remains afloat after a ship has sunk, and jetsam is cargo or equipment thrown overboard from a ship in distress. The precise meanings are lost in the common phrase flotsam and jetsam, which describes useless or discarded objects. The phrase is sometimes used to describe items floating or washed ashore, but it has also been extended into metaphorical use for any accumulation of odds and ends.
