Mathematical Sabbath 

One day in a week when you abstain from any mathematical activity—no preparing, no problem solving or posing, no marking—to give the left part of your brain a day off, while inviting the right part to take over.
Your mathematical sabbath could prove to be the most productive day of the week, as you let your logical mind recover and reenergize from a hectic week.

Mathematical Shrine 

A shelf that displays your math memorabilia (abacuses, slide rules, polygonal stamps, math-related postcards, 3D wooden puzzles, topology toys, …) that are likely to be a topic of conversation as friends and strangers visit your home.
Ian’s mathematical shrine is made up of origami polyhedrons, magic card tricks, Napier’s rods, vintage calculators and clocks, and Lilliputian math books.

Mathematical Sensitivity

When a math teacher decides not to hurt the feelings of their weak students, by insincerely using large numbers and symbols to grade their test paper—for example, a student receiving back their exam paper with a score of (√81)/90 or 4²/100, mistaking it for 81/100 or 42/100.
Some parents object to teachers’ “mathematical sensitivity” or fake feedback, preferring that they’d tell their child the painful truth how poorly they had performed in their math test.

Mathematical Steroid 

Short-term success in math, whereby exam-smart teachers and tutors drill or spoon-feed students, by getting them to memorize modeled solutions of questions that are likely to appear in the coming examination based on previously set questions from past exam papers.
It’s not surprising that most university students in Singapore, who are reading for a degree in math, struggle with their courses because they grew up on mathematical steroids in high school.

Mathematical Slowies 

Non-trick or non-tricky math questions that you can do at your snail’s pace without worry or fear of having to sit for any killer test or exam—they are recommended for self-confessed folks who pride themselves of being “hopeless at math,” or not being born with the “math gene.”
Mathematical slowies are the opposite of “mathematical quickies,” which are generally solved with some insight, and often accompanied by an occasional aha! reaction.

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."
