The Original Slush Fund

If you follow politics (or, more likely, a politics-themed TV sitcom or drama) you’ve probably heard the term “slush fund” — and usually, it’s tied to something shady. A slush fund is money set aside for unofficial, often unethical, and sometimes illegal uses. It’s the kind of fund that no one really wants to talk about, and if they do, they don’t want to explain too much about it. If someone has a slush fund, you could say that there’s something fishy going on.

And you’d be right — literally speaking.

The word “slush” dates back to at least the mid-1600s, referring to the cold, wet muck that is formed when snow begins to melt. It’s unpleasant texture must have made an impression of the people of the day because a century or two later, “slush” took on a new, second meaning — at least, if you were on a boat.

Salt pork — salted (for preservative reasons) pieces of pork belly — was a staple on fishing and whaling ships of the early-to-mid 1800s. Crews aboard those ships spent a lot of a time at sea, and salt pork was a good, long-lasting protein source in an era before refrigeration. Salt pork was typically fried, and as the ship’s voyage continued onward, fat, grease, and other waste products would build up in the cooking vats. This residue became known as “slush,” likely because of its similarities to the melted snow seen back on land.

But this pig-created slush wasn’t just thrown overboard as waste — it turned out to be useful; as One Word a Day notes, “sailors used it as a lubricant and to waterproof the rigging and sails on their ships.” So they kept it around, and when their whaling or fishing expeditions ended, they typically still had a large amount of slush left over. And it turned out, there was a market for the stuff. Other ships could also use it to help their sailing efforts (before they started cooking up their own salt pork). As The Straight Dope notes, it could also be used by candle and soap makers. Once back on land, there were plenty of people who would gladly buy the slush off the ship’s cooks or other sailors.

That turned out to be a boon for the crew. Because the slush was a byproduct of the efforts to feed the crew, ship owners rarely, if ever, cared about the value of the slush itself — to them, it was waste created by the cost of doing business, not an asset. So when the sailors sold off the slush, they kept the money for themselves and their crewmates. Per Merriam-Webster, “The money from the sale of slush was reserved for the crew of the ship, and would be used to purchase items, such as musical instruments or books, which were not considered necessary enough that a country’s navy, or a ship’s owner, had to provide them for a crew.”

According to the Online Etymology Dictionary, as a result of this usage, the phrase “slush fund” first appeared in our collective lexicon in 1839. It would take a generation or two before it gained its current, negative connotation often implying bribery. And with that came another term for financial shenanigans, which also comes from the use of salt pork byproducts to fund sailors whims: “greasing,” meaning “bribing.” The Etymology Dictionary explains “The extended meaning ‘money collected for bribes and to buy influence’ is first recorded 1874, no doubt with suggestions of ‘greasing’ palms.”

Bonus fact: The term “slush fund” didn’t originally imply anything untoward — the association with bribery came later, as noted above. And the same is likely true for the word “bribe” itself. Per the Online Etymology Dictionary, “bribe” comes from the Old French term of the 14th century of the same spelling meaning “a gift,” and specifically, “bit, piece, hunk; morsel of bread given to beggars.” It took 200 or so years before the modern, sketchy meaning developed, and it’s unclear why.
