Instrument Flight Rules

The Instrument Flight Rules (IFR) are a set of rules for flights where it can not be assumed that pilots will be able to navigate their aircraft or maintain separation from obstacles, terrain, and other aircraft by reference to features outside the cockpit.

All flights which take place in Instrument Meteorological Conditions (IMC) must be conducted in accordance with the Instrument Flight Rules (IFR). However, flight under the Instrument Flight Rules (IFR) may also be conducted under Visual Meteorological Conditions (VMC).
Looks like the weather forecast is predicting IMC over the airfield tomorrow. We better change our flight plan from VFR to IFR for tomorrow's flight.

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."
