It's actually spelled cecum and all mammals have one, not just rats. It is at the end of the ileum, which is connected to the jejunum, which is connected to the duodenum. The cecum is a small pouch where the small intestine and large intestine meet. Those 4 parts make up the small intestine.
The cecum looks like a small thumb connected to the small intestine.

“You’re just scum!” 

“You’re just scum!” — Nikki Haley’s succinct description of Vivek Ramaswami that caused him to have a gas face in the middle of the MSNBC televised debate on 11/08/2023. It was an Indian on Indian shoot out and we are certain that Vivek shot first.

He missed.

And like Han Solo in the Star Wars retcon, Nikki moved her head drew her blaster and nailed “Tandoori Greedo”.

If you come at the queen; then you better not miss! And she did that shite wearing the five inch heal that he criticized; and she looked good doing it, too.
Ramaswami: Your daughter’s on Tic Tock; get your own house in order.

Haley: Keep my daughter out of your mouth; “You’re just scum!”

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."
