morbid validity 

something horrible or morbid in the written word, on film, or in an image, that explains itself in a way you can understand and/or appreciate. creating something horrible or morbid that is not simply to shock, scare, or disgust people.
Some of Edgar Allen Poe's work, like the Cask of Amontillado, had a sort of morbid vailidity behind it. (or) I saw that horror movie, Final Destination, and it seemed that most of the killings were done to shock people, it lacked morbid validity compared to a movie like Silence of the Lambs.

Law of Spectral Logical Validity

The principle that logical validity exists on a spectrum between absolute and relative, with infinite gradations and multiple dimensions. Under this law, an argument isn't simply valid or invalid—it's valid to some degree, in some logical systems, under some interpretations, for some purposes. The law of spectral validity recognizes that validity is not binary but continuous, that arguments can be more or less valid depending on the standards applied, and that the question isn't "is it valid?" but "where on the spectrum of validity does this argument fall?" This law is essential for understanding debates between different logical frameworks, where each side's arguments are valid within their own system but may appear invalid in another.
Law of Spectral Logical Validity Example: "She evaluated his argument using spectral logical validity, mapping it across multiple dimensions: validity in classical logic (high), validity in paraconsistent logic (medium), validity in fuzzy logic (depends on truth values), validity in everyday reasoning (pretty good). The spectral coordinates explained why the argument worked for some audiences and failed for others. She stopped calling it invalid and started understanding where it lived."

Law of the Fallacy Validity

The principle that under specific conditions, what appears to be a fallacy can actually be valid reasoning. The law acknowledges that context matters: an argument that commits a fallacy in one setting may be perfectly reasonable in another. Ad hominem, attacking the person, is fallacious in formal debate but valid when assessing credibility (you wouldn't trust a tobacco company's research on smoking). Appeal to authority is fallacious when the authority is irrelevant but valid when expertise is genuine. Slippery slope is fallacious when speculative but valid when causal chains are real. The law of the fallacy validity reminds us that fallacy labels are not absolute; they're tools, not weapons. What matters is not whether an argument fits a fallacy pattern but whether it's reasonable in context.
Example: "He accused her of ad hominem for mentioning the speaker's industry funding. She invoked the law of the fallacy validity: attacking the person is valid when their credibility is relevant. The funding mattered; the ad hominem was justified. He called it a fallacy; she called it context. She was right."

Appeal to Validity

A fallacy where someone argues that because an argument is logically valid (if premises true, conclusion must follow), it must therefore be sound (premises actually true). Or more commonly, using "that's not valid" to dismiss arguments that don't fit classical logical forms. The appeal is fallacious when it confuses formal validity with truth, or when it treats validity as the only criterion for good argument. An argument can be perfectly valid and completely false if its premises are wrong.
"I made an argument based on probability and context. Response: 'That's not logically valid!' They meant it didn't fit syllogistic form. But probabilistic arguments aren't supposed to be deductively valid—they're supposed to be inductively strong. Appeal to Validity: judging all arguments by standards that only apply to some."

Frothability 

The measure of an emotional and over zealous consumer in an upwardly charging market, also known as a bull market. It's characterized by rising asset prices, increased investor confidence, and favorable growth in the markets, bro.
The frothability was evident as over-zealous consumers eagerly engaged in bidding wars, driving property prices to unsustainable levels reminiscent of previous speculative bubbles.

Soul digger

A man who dates women with the sole purpose of exploiting their time, energy, and labor while he sucks the joy and happiness from their lives.
"That guy's a soul digger. He'll expect you to work full time, but you'll be doing all the cooking, cleaning, laundry, shopping, and childcare while he plays video games or watches TV."

pod person 

A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.

A dead drop is a location used to secretly pass items between two people, without requiring them to meet.

Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.

A common place is to duct tape the item to the underside of a toilet cover in a public restroom.

A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."
