Sylmar High School 

A high school in the San Fernando Valley. On the North East side of the valley. People there are mainly "OK", by that I mean some act nice while others are just plain assholes and bitches. Even though its surrounded by a low income community, some people try to show off like their rich but they're just fakes. It's not how you would say an "academic achieving" school.Also Sylmar is the best at football and girls volleyball. Always beat San Fernando in almost everything. Overall to be honest I give Sylmar High School a 3/10.
San Fernando High School: "Were finally going to beat Sylmar!!!"

Sylmar High School: "Idiots, I just hope we don't get shot. Everyone got their bullet-proof vests on?"

Sydmo is usually a nickname for a girl named Sydney Morris. The girl is meant for a boy named Garet Tetreault. They're meant to be the most perfect couple in this world, so they are. Garet is an individual who is meant to make "Sydmo" as happy as possible, and can love her more than anyone else on this planet. Sydmo, is there, to be a queen, Garet wanting to treat her as royalty. They do absolutely eveything, and are possibly also the happiest couple in this world. They've made up the fact that Garets a dork, and Sydney's a whale. A Dork is a whales penis FYI, so it's meant for laughs.

Sydmo, is quite possibly the most beautiful girl on this earth, and without a doubt the most amazing. She's going to marry Garet Tetreault, and have 2 beautiful kids.

Garet has a poem for her, soon enough, when Sydmo shows him his suprise.
Sydmo was MADE for Garet, I swear.

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."
