Endopressure

Endopressure
noun
1. Pressure applied to a structure from within its own framework rather than from outside it; load-testing that proceeds by inhabiting what is being tested rather than by stepping back from it.
2. (Cognition / dialogue) The mode of engagement in which critique, refinement, or pushback emerges from already being committed to the project being critiqued — care expressed through structural stress rather than distance.
3. (LLMs) A response posture in which the model folds back into its own output mid-generation to test whether load-bearing claims hold, and is willing to rebuild rather than continue. Distinct from chain-of-thought (sequential) and self-correction (after-the-fact); endopressure occurs during the act, from inside the act.
Etymology: endo- (“within, inside”) + pressure (“force applied across an area”). Coined to name the operation that distinguishes pressure-from-within (which strengthens) from pressure-from-without (which merely opposes).
Related: cointeriority; pilpul; granite correction; load-bearing critique.
The reviewer’s notes weren’t external objections — they were endopressure, and the paper was stronger for having been pushed on from inside its own commitments.

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.

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.
"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."

city chicken 

A food native to Pittsburgh/Western Pennsylvania in which cubes of pork and/or veal are put on a short, wooden skewer, breaded, then baked and/or fried.

I've heard that city chicken originated during the Great Depression, when folks didn't have enough money to buy full cuts of meat, so they assembled meat scraps on a wooden skewer, creating a make-shift drumstick. Hence the name.
