fuzzy logic 

The Logic from which only the fuzzy can understand. Not for the kind face; Deeply thought out facts on light issues not discussed in simple english.

Not usually found in normal everyday conversations.
(orginated from OUTKAST AQUIMENI- GEORGE CLINTON)
"the clouds are meloncholy sky electric blue, Mama earth is tossin an cryin because of you, Raining CATs and Jackals, No shakles desinigrate to residue, silly mortals haven't a clue..."
- Andre 3000

" the sense is not how he sounds, but in the words, meanings, and emotions behind his fuzzy logic. "

fuzzy logic 

Profile pictures on MySpace or other social networking sites in which a woman (or man, these days) wears pants that are cut so low you can see his or her pubes.
You: Wow, have you seen Henrietta's mom's MySpace pic? She's a little old to be wearing jeans that low.

Me: Yeah, you can see her pubes in that fuzzy logic, dude.

You: I wish Henrietta would post a fuzzy logic for her Facebook photo.

Me: Yeah, but I kind of like the digital divide she posted. I'm a tit guy when it comes right down to it.

You: Yeah, I'd take digital divide over fuzzy logic any day.

Fuzzy Logic Theory

A formal system that extends classical logic to handle degrees of truth rather than the binary true/false. In fuzzy logic, a proposition can be 0.2 true, 0.8 true, etc. It uses truth values in the continuous interval 0,1 and defines logical operators (AND, OR, NOT) accordingly. Fuzzy logic theory underpins control systems, decision support, and approximate reasoning. It is not “vague” but mathematically rigorous, designed to model the inherent imprecision of natural language and real‑world measurement.
Example: “Fuzzy logic theory powered the washing machine that sensed ‘slightly dirty’ vs ‘very dirty’ and adjusted the cycle—no binary decisions, just graceful gradations.”

Fuzzy logico‑epistemology

A logical framework that replaces the classical true/false binary with degrees of truth, typically represented by real numbers between 0 and 1. Fuzzy logico‑epistemology recognizes that many real‑world statements (e.g., “the weather is hot,” “the solution is acceptable”) are matters of degree, not crisp categories. It is especially useful in control systems, artificial intelligence, and decision theory, where precise boundaries are impossible. Epistemologically, it challenges the idea that knowledge requires certainty, allowing for graded beliefs and gradual transitions between ignorance and full confidence.
Example: “The thermostat used fuzzy logico‑epistemology to decide how much to cool the room—not a binary on/off but a continuous adjustment based on how ‘too warm’ the temperature actually was.”

Fuzzy Logic

A multi-valued logic where truth values vary continuously between 0 (false) and 1 (true), allowing handling of imprecision and vagueness. It contradicts the principle of the excluded middle (something is either true or false). Used in control systems (air conditioning, ABS brakes), artificial intelligence, and decision theory. It is not "logical relativism" – it has well-defined rules.
Fuzzy Logic Example: "In fuzzy logic, the statement 'today is hot' can have a truth degree of 0.7 if the temperature is 28°C – neither completely true nor false, and an air conditioner uses that to adjust ventilation."

murderhobo 

In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.

The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.
