From The First Church Of Satan (FCOS) Come The Five Commandments Of Satan (FCOS):

1) Thou shalt love thy neighbor's wife until her husband comes home from work early one day, catches you in bed with her & kicks your ass! 2) Thou shalt not covet what I have stolen from you because you shall never get it back! 3) Thou shalt not take my name in vein unless if you are using a syringe containing all of the letters of my name within it, but you must never share the needle! 4) Thou shalt not bow down before any other god but me or I will come up from behind you & get busy! 5) Thou shalt turn the other cheek until your neck twists around & breaks, your spinal chord rips in two and your head falls in your lap!
"I prefer the 42 Laws of Ma'at over the FCOS and the Ten Commandments."

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."
