Cyberspace: "Cyberspace" is one of those words that has quickly traveled from science fiction into the mainstream vernacular. The word comes, not surprisingly, from that cyberpunk master William Gibson, appearing first in his 1982 short story Burning Chrome. (Gibson actually first read the story aloud in 1981, but it wasn't published in Omni until the following year.) Here, "Cyberspace Seven" is the name applied to a computer, but the concept of cyberspace gets a more complete definition in Gibson's 1984 novel Neuromancer:

Cyberspace. A con sensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts . . . A graphic representation of data abstracted from the banks of every computer in the human system. Unthinkable complexity. Lines of light ranged in the non space of the mind, clusters and constellations of data. Like city lights, receding....

Warp speed is an example of a phrase that entered the public consciousness through science fiction and eventually gained enough popularity to end up in the dictionary. The expression was popularized on the science-fiction show Star Trek in the 1960s. On the show, warp speed referred to a specific concept, namely the idea of faster-than-light travel. Within a relatively short period of time, Star Trek gained a devoted and intense following. Fans were soon discussing the fictional concepts of the show, including warp speed, with great enthusiasm. Eventually, the term warp speed was adopted by the general population. In the process, however, it lost its specific fictional meaning and came to mean simply "the highest possible speed."

To understand, get, be hip to.

Grok may be the only English word that derives from Martian. Yes, we do mean the language of the planet Mars. No, we're not getting spacey; we've just ventured into the realm of science fiction. "Grok" was introduced in Robert A. Heinlein's 1961 science fiction novel Stranger in a Strange Land. The book's main character, Valentine Michael Smith, is a Martian-raised human who comes to earth as an adult, bringing with him words from his native tongue and a unique perspective on the strange, strange ways of earthlings. "Grok" was quickly adopted by the youth culture of America and has since peppered the vernacular of those who grok it, from the hippies of the '60s to the computerniks of the '90s.

I kept thinking of The Moon is a Harsh Mistress...and then, no that's not it!I think Moon is about my favorite Heinlen, which may be why.

In the context of Orwell's "Nineteen Eighty-Four" is means constant, permanent, required government surveillance, even in the citizen's 'private' life.

Now we use the phrase when government agencies put up cameras in public places, where no expectation of privacy exists.

We also use it as the concept behind a TV show in which people volunteer to be watched constantly by a private entity, an entertainment corporation, for the amusement of private citizens.

To express the idea that a completely made-up word deserves to be an actual word.

Among a few others that didn't stick.

Oh, and 'vorpal' which only Dungeons and Dragons players may appreciate.

which is the name for that whole category of words like chortle.

We know exactly how old yahoo is because its debut in print also marked its entrance into the English language as a whole. Yahoo began life as a made-up word invented by Jonathan Swift in his book Gulliver's Travels, which was published in 1726. The Yahoos were a race of brutes, with the form and vices of humans, encountered by Gulliver in his fourth and final voyage. They represented Swift's view of mankind at its lowest. It is not surprising, then, that yahoo came to be applied to any actual human who was particularly unpleasant or unintelligent. Yahoos were controlled by the intelligent and virtuous Houyhnhnms, a word which apparently did not catch people's fancy as yahoo did.

Too bad there are no Houyhnhnms IRL.

... used in fiction later. "Robot" was introduced in a play way back in 1920 by Karel Capek.

Some engineers prefer "tinstaafl," because they prefer to use "is" rather than "ain't."

...There Ain't No Such Thing As A Free Lunch...as for robot, I knew about Capek, of course--but surely, a play counts as "fiction"...by the way, Capek's *War With the Newts* is wildly funny, and heartbreaking...
