Episode Glossary

This article lists down the different terms and phrases used in each episode and its definition.

Term 1: El Psy Congroo
"El Psy Congroo" is the password that Rintarou Okabe uses whenever he ends a conversation. However, it is revealed that the supposed conversation he ended did not actually exist because Rintarou usually turns his phone off. The phrase is a combination of greek and latin meaning "To Harden the Mind". The exact origins of this phrase is unknown, but it is similar to a something posted by a BBS user: "La Jodaso Stiana".

Term 2: "Organization"
'''This is an agency Okarin refers to as a group who he works in joint with involved with all things SCIENCE. It is a highly secret group who is sought after by many an opposing organizations, whose secrets would be vital to radical change. This is the initial irony to the series, as something imaginary becomes all too real.'''

Term 3: Metal Oopa
The Metal Oopa is one, if not the, rarest of a colletive vending item called Oopa. While this item is considered a child's type, some collect them for their rarity value. Revealed later on in the series, it is noted that the same Metal Oopa Mayuri finds in Episode 1 is actually life-saving in regards that if for not Mayuri would not to have bought the Oopa while on her way to find Okarin, she would have met the murderer and suffered the same fate as Kristina would have in that timeline - buying the Oopa diverts her and prevents her from walking into him, having Kristina die as intended. [citation needed] It is also said that the Oopa is also the same sort of metal used for the time machine in one of its contraptions. [citation needed]

Term 4: Alpacaman
This alphaca with a man's face is a conflicting provider of information and support and a rival in study for Okarin and his lab - the actual character is one from a television series.

Term 5: Hououin Kyouma
The main protagonist of Steins;Gate, Okabe is a self-proclaimed mad scientist and often refers to himself under the alias of Hououin Kyouma, which is also the name he uses to introduce himself to other people. Mayuri and Daru refer to him by the nickname Okarin. He also uses this alias when browsing @channel.

Term 6: The Choice of Steins' Gate
Stein is the overrulling force that is science as well as the guide of science, as if a sort of God of Science. This is Okarin's half- humored belief in science. The Gate is for the access of knowledge.

Term 8: Landlord
Mr. Braun, the manager of a small electronics store including televisions, microwaves, and such is also the property owner of the apartment. It is shown that he does not dislike Okarin, but finds his antics to be very disruptive to the propety.

Term 9: Hostage
Explained later on in the series, Mayuri is said to be Okarin's hostage. This is because she was traumatized by her grandmother's death to the point where she would visit her grave daily during younger years. One day, Mayuri reaches up towards the sky to a beam of light, and Okarin runs to hold her as he announces that he won't let her go anywhere because she is his hostage - he was afraid she would be taken into the heavens and she would not be with him. It's a non-affectionate way of saying he will never have him leave her if he can help it.

Term 10: Phone Microwave (Name Subject to Change)
This is actually the full name of the machine used for the initial time-travel related plot in the begining of the series. When a message is sent to the microwave from a phone, it activates it remotely - how convinient! This is the base concept for the time machine later on.

Term 11: Gel Banana

Term 1: SCIENCY
SCIENCY (in fact, SCIENCE) is the most famous scientific journal magazine in the world and is the academic journal of the American Association for the Advancement of Science.

Term 2: Yanabayashi Shinto Shrine
This is the shrine that Mayuri's sibling Ruka helps manage.

Term 4: "However, she's male"
In regards to Ruka, "It's a trap!" - at least at some point.

Term 5: "Oh-ha~!"
'Part Time Warrior' says this. It's signifigant because it's terrifying in a video on YouTube of her freezing time with. This has absolutely no relevance or importance in the series and should be honestly omitted.

Term 6: @channel
This is the fictional equivilant to a Chan such as 2ch, 2chan, and 4chan, with the first being implied. This is in reference across many anime and manga.

Term 8: SERN

Term 11: World Line

Term 12: IBN 5100
An old computer developed by IBM, the IBN is the anime equivilant. It is a computer made in 1975 that runs very simple coding that is disregarded on in future computer models, causing a very short stock to have ever been produced. This apparently is imperative to the use of a time machine, as said by John Titor.

Term 13: Mayushii Nyan-Nyan
Mayuri does a small position at a maid cafe as a catgirl maid, where they all say "nyan~" at the end of their sentences. It's quite cute.

Term 1: HENTAI
In Japanese, means 'pervert'. Kurisu uses this quite often for Daru. He's a perv. 'Nough said.

Term 2: Christina (Kurisu-tina)
Another name given to Kurisu by Okarin. He teases her with this name because it is slightly awkward - it is a continent neutral name of American and Japanese origin. This is because her father did business across seas, and predicted that she would be more suited with an easier name for both countries.

Term 4: The Zombie
One of the many names given to Kurisu by Okarin. One could suggest that he enjoys teasing her (might develop into a relationship later on).

The 'satelite' which crashed into the science facility in episode 1.

Term 6: Shining Finger
In reference to the Kung Fu skill from the protagonist of Gundam G series, this is the nickname given to Moeka Kiryu by Okarin because she always communicates through text messages.

Term 8: LHC (Large Hadron Collider)
This is a device used by both real world CERN and fictional SERN to collide atoms in attempt to create extreme forces of energy and such. It's the scientific way of 'knocking things together until something interesting happens'. It runs underground in a ring. Not to be confused with a dyslexic's Large Hardon.

A point in time and place selected for existing. In otherwords, it's just a place.

Term 1: Round-Table Meeting
A term meaning that members of a group will equally discuss a subject as peers to solve a problem or examine as situation - their table is rectangle, so it's funny.

Term 2: Nostalgia Drive (Nostalgic Journey that Crosses Over Time)
NOSTALGIA DRIVU~ is a fancy term Okarin uses. He uses a lot. They're funny, so get used to it.

Term 3: The Mail that Leapt Through Time
This is Itaru Hashida's suggestion for a name that would describe the e-mails they send back in time. The phrase is in fact a reference to the movie "The Girl Who Leapt Through Time", a story of a girl who is able to travel back in time. It's sad.

Term 4: D-Mail
Kurisu's suggestion for the term to be used for the messages they send back in time. It is a shortcut of Mayuri's suggestion "DeLorean Mail" and it eventually becomes the "official" term the Future Gadget Lab would use to pertain to the messages. DeLorean is probably a reference to the Back to the Future movie series, wherein the car used by the main characters is a DeLorean DMC-12.

Term 6: Kerr Black Hole
This is a black hole that spins - most black holes do not have an axis, as they 'suck in' all matter and space, practically folding in on themselves (not to be confused with collapsing). A Kerr Black Hole rotates on its axis as it pulls anything, but rather immediately into, can somewhat orbit matter around it infinitely. This is why it is associated with time travel, as supposedly the more you can approach the speed of light, the faster time becomes - if you were to somehow go faster than light, time could be transversed in either direction.

Term 7: Event Horizon
Basically, the "point of no return" around a black hole - nothing can escape the gravitional pull, not even light. This is the location in which nothing can effect anything outside. Everything in existance is considered above the Event Horizon, and anything inside is below it. In other words, anything is possible.

Term 8: My Favorite Right Arm (Dependence on One's Right Arm)
In otherwords, something that cannot be replaced and is absolutely vital.

Term 9: Super Hacka
Daru self proclaimed "Super Hacker" is called "Super Hacka" by Okarin.
