Ion
Coined in 1628 in France by Descartes, who did not believe in atomism or a universe consisting of moving particles, but was mad at his partner Gassendi at the time for achieving some success through publishing a paper on the existence of those very subjects. Descartes publicly derided Gassendi by fabricating "ions", which Descartes described to the public as "you know, like, lightning? Those are ions, dudes."
The scientific community of the time agreed that ions were indeed awesome, certainly more so than atoms, and Gassendi's theories fell out of favor. Descartes utilized the interest around his fake theorem to become a minor celebrity and went on speaking tours. The money from these tours was parlayed into many ion merchandising offshoots. Most famous of them was a product called "ion tonic", which claimed it could cure any sort of malady one had by "re-energizing the body". (Although the product was mostly cocaine distilled in syrup.)
A jealous scientist lover, Gassendi reacted by exposing the fraudelence of Descartes claims, even though exposing ions as frauds hurt Gassendi's own position as a positer of atomism. Brought low, Descartes apologized to Gassendi through a series of drunken letters. The two reunited and lived together in "a very serious relationship" until Descartes's passing in 1650.
In the 1800's, when electrically charged atoms were discovered, they were dubbed "ions" in honor of the fiery, tempestuous relationship between Gassendi and Descartes. A kind of relationship that many scientists, to this day, wish they could experience. (With real people, not just science.)
Interim
Created during the Spanish Inquisition in the 17th century when unemployment briefly became a state crime and idleness was considered a form of heresy, the term "interim" was utilized to signify to Inquisitors that one was "between jobs", i.e. "in the interim I've been traveling...doing some painting".
The term came back into popular use during Herbert Hoover's American presidency when, during a speech in 1931, a frustrated Hoover tried to soothe the nation regarding the persisting Depression. "My fellow Americans. Just...this whole Depression, it's an interim thing for America. We're just taking a break, you know? And I encourage this. If you need to get your shit together then get your shit together. The economy...don't get me wrong...it's important. It's SO important. But we as a nation need some time to get it right or otherwise this Depression will just continue. So, uh...stay the course. And if you're listening to this then I'm glad you haven't yet sold your radio to buy food."
Awesome
Though its exact origin is unknown, this term is believed to have developed in the Mesopotamian valley along with the first literate human societies. Its first recorded use appears in Sumerian text regarding the implementation of irrigation. The text roughly translates as, "So they dug this furrow? In the ground next to the river? And the water just came down the furrow on its own? And now we don't have to lug buckets of water around? I don't know what I'm going to do with all of this free time! It's awesome!"
Hammock
Invented in 1520 by the dread pirate Pedro Menendez de Aviles, who required a bed that would move with the rocking motions of the ship. It was dubbed "hamaca", which in the colloquial Spanish of the time meant "woozy in bed". The invention eventually proved more lucrative than Captain Pedro's plunderings and de Aviles remains one of the few pirates in history to actually retire successfully. Even after retirement, Pedro continued to sleep in hamacas, reportedly on the advice of his first mate/marketing director who urged that his personal use of his product "brings a lot of integrity to the brand".
