Jacobian Slip

A Jacobian Slip occurs when one mishears a word or phrase and questions the misheard phrase, thus revealing something about their internal thoughts.

Like how a Freudian slip can reveal internal thoughts, but with mishearing rather than mis-speaking.
A: Yo get me two large fries and a shake after you get gas
B: You want two large guys shakin’ their ass?
A: What the fuck
B: My bad, that was a Jacobian slip

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."
