A term that was popular in the early 2000's and is an acronym for "designated ugly fat friend." In modern day, this term is only used by douches who can't keep up with current slang, and by stupid ass middle schoolers who think they are the shit because of the 2015 movie of the same title that attempted to resurrect the term and make it "cool."

Stupid Person 1: Why is that ugly bitch hanging out with those hot girls?
Stupid Person 2: She must be the DUFF.

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.

Whale

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."
