The difference between crap and *****?
The origin of crap is still being debated. Possible sources include the Dutch Krappe; Low German krape, meaning a vile and inedible fish; Middle English crappe, and Thomas Crapper. Where crap is derived from Crapper, it is by a process know as, pardon the pun, a back formation. The World War I doughboys passing through England brought together Crapper's name and the toilet. They saw the words T. Crapper---Chelsea printed on the tanks and coined the slang "crapper" meaning toilet.
*****? Certain types of manure used to be transported (as everything was back then) by ship. In dry form it weighs a lot less, but once water (at sea) hit it. It not only became heavier, but the process of fermentation began again, of which a by-product is methane gas.
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. BOOOOM!
Several ships were destroyed in this manner before it was discovered what was happening.
After that, the bundles of manure where always stamped with the term "S.H.I.T" on them which meant to the sailors to "Ship High In Transit." In other words, 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.
You DID ask.
