Derived from Robert Louis Stevenson's popular novella, "The Strange Case of Dr. Jekyll and Mr. Hyde"

Dr. Jekyll is a respected doctor and friend of both Lanyon, a fellow physician, and Utterson, a lawyer. Jekyll is a seemingly prosperous man, well established in the community, and known for his decency and charitable works. Since his youth, however, he has secretly engaged in unspecified dissolute and corrupt behavior. Jekyll finds this dark side a burden and undertakes experiments intended to separate his good and evil selves from one another. Through these experiments, he brings Mr. Hyde into being, finding a way to transform himself in such a way that he fully becomes his darker half.
"If I ever needed further justification for my experiments, gentleman; you have just provided it."

The Dr in Dr Jekyll and Mr hyde orrrr
One of the nicest people you’ll ever meet, if they chose their name they’re probably autistic (or really really really love classic literature, or both). Chances are they’re really tall and have a good taste in music

Jekyll and Hyde Parenting 

A style of parenting that provides a full spectrum of emotional and psychological experiences to a child vis-a-vis the parents’ instability and addictions which lays the groundwork for years of in-depth psychotherapies in which the child, throughout their lifespan, has the opportunity to undo the warp and find some semblance of balance and potentially, a sense of a true self.
Yup, at our house it was nose-to-the-grindstone discipline during the week and then Mr. Toad’s Wild Ride when the weekends rolled around; my parents were practicing devotees of Jekyll and Hyde Parenting.

Jekyll & Hyde 

Jekyll & Hyde was a Broadway musical in the late 90's written and composed by Leslie Bricusse and Frank Wildhorn. It's based (if rather loosely) on the novel "The Strange Case of Dr. Jekyll and Mr. Hyde" by Robert Louis Stevenson. The musical enjoyed a decent Broadway run and was a rather good show.
Unfortunatly, towards the end of its run David Hasselhoff was cast in the role of Jekyll/Hyde. He completely massacred the music and sadly his pitful performace has been captured on DVD for all eternity. Fans of the show or "Jekkies" often harbor an intense hatred for Hasselhoff because of the stigma he set for the show.
Jekyll & Hyde has several memorable songs including "This is the Moment", "A New Life", "In His Eyes" and "Bring on the Men" (which was not actually featured in the Broadway version").
The show has a number of devoted fans (Jekkies) and can still be seen all over the world. Recently, it has been annouced that "Jekyll & Hyde" will soon be made into a major motion picture. It is scheduled to come out in 2007 however, the cast is still unknown at the moment. The film is bound to be successful and will most likely result in a surge of the fan base, much like in the case of "The Phantom of the Opera" (perhaps the most extrodinary musical/story ever (I myself have been a proud "phan" for 9 years)). Many fans eagerly await the film's opening and are completely baffled as to who will be in the cast (hopefully not David Hasselhoff).
Person 1: "I just saw "Jekyll & Hyde", it was really good, I was suprised. I've heard bad things about the show, apparently David Hasselhoff used to be in it."
Jekkie:"David Hasselhoff is the bane of my existance. I'll rejoice in his death."
Person 1:".......k...."

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."
