Hilbert AIDS 

A disease rapidly spreading throughout the SUNY Albany campus and surrounding area. Very contagious, can be spread by blood, semen, even saliva. All you need to do is kiss someone to get the HAIDS.
I made out with that girl and now through a chain of 6 people I have the Hilbert AIDS!

Hilbert Space 

Named for its putative inventor, mathematician David Hilbert (who some claim found the solutions for Einstein's equations before "L'il Albie" did himself), Hilbert Space is a concept which has been often applied in mathematics, quantum mechanics, and in general metaphysics (for instance, concepts like "parallel universes").

In short, a Hilbert Space is a mathematical construct such that within any plenum of n-dimensional spaces there exists an infinite number of said Hilbert Spaces (subsumed within an n+1 dimensional superset). Fancifully, science fiction writers point to the infinite plurality of 4D Hilbert Spaces that could exist within our "normal" 5D continuum, and suggest that each such Hilbert Space may really exist and that these Hilbert Spaces could be engendered by time-travel to the past. Thus, each 4D Hilbert Space in a 5D superset of "Universes" could possess a unique history, entirely different from all other universes contained within the 5D "Universe".
Mozart's 14th Symphony (K. 114, composed c. 1774) contains encrypted fragments of instrumental speech synthesis (in English) which describe an alternate Universe History (different from our Universe), where Nicholas Meyler was President of the United States, and where Princeton University is mocked for its intellectual feebleness (possibly due to some degree of idolatry for Einstein's Theory of Relativity, which Mozart proved to have loopholes and flaws 130 years before Einstein even published it as "The Electrodynamics of Moving Bodies").

Deciphering Mozart's musical cryptography provides physical evidence that Hilbert Spaces may be entirely real, and not merely imaginary constructs.

From Shakespeare's Merchant of Venice, Shylock's Daughter.

A woman known for her poetry, creativity and beauty but she never lets on that she is aware of it. She would rather support her Love's interests than become too involved in her own.
Man, Aaron is so lucky, he hooked up with a total Hulburt.

Yeah, he will go far with that hot little Hulburt at his side.

Hilbert space 

A complete inner product space. Since every inner product defines a norm, a Hilbert space is necessarily a Banach space.

Up to equivalence of norms, there's only one distinct n-dimensional Hilbert space for each n, namely R^n.
The space of all continuous real-valued functions on the closed interval from 0 to 1, with the inner product given by the integral of pointwise absolute-value products, is an infinite-dimensional Hilbert space.

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.
DM: The sad little orphan girl tugs at Steve's trenchcoat to get his attention, and ask for help saving her pet dog from...
Steve: I'd like to roll a strength check against strangling the orphan.
Dave: I call dibs on the dog.
DM: You murderhobos disgust me.

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."
