When the voyage was over, the surplus grease was sold, and the money was put into a “slush fund” to be shared by the enlisted men.

By 1839, when a ship returned to port, any surplus supplies or battle-damaged equipment was also sold and the money added to the profits from the grease in the slush fund.

These days, a “slush fund” refers to a stash of surplus money.
