(a.k.a. "That Don't Mean Shit!")
In the 16th and 17th centuries, everything had to be transported by ship and it was also before the invention of commercial fertilizers, so large shipments of manure were quite common.
It was shipped dry, because in dry form, it weighed a lot less than when wet, but once water (at sea) hit it, not only did it become heavier, but the process of fermentation began again and a by-product is methane gas that formed again.
As the stuff was stored below decks in bundles you can see what could (and did) happen. Methane began to build up below decks and the first time someone came below at night with a lantern...
Several ships were destroyed in this manner before it was determined just what was happening. After that, the bundles of manure were always stamped with the instruction ' Stow high in transit ' on them, which meant for the sailors to stow it high enough off the lower decks so that any water that came into the hold would not touch this volatile cargo and start the production of methane.
Thus evolved the term ' S.H.I.T ', (Stow High In Transit) which has come down through the centuries and is in use to this very day. You probably did not know the true history of this word. Neither did I.
I had always thought it was a golf term.
This story is a hoax. There is no historical evidence that "Ship High in Transit" aboard ships was the origin for the word "shit." The eRumor has circulated on the Internet since about 2000. This issue is specifically addressed by the folks at the Online Etymology Dictionary who say that "Despite what you read in an e-mail, 'shit' is not an acronym."
The Merriiam-Webster dictionary dates the word back to 1526 and says that it is from the Old English scite and akin to a related word, "scitan", and means to defecate.
A writer for the Online Etymology Dictionary points out that the use acronyms didn't develop until the 20th century so a word that is hundreds of years old would not have originated as an acronym.
