When something in a show receives a Fan Nickname
which originated with the show's production team. Doesn't count if it's a technical term which can be applied to unrelated shows. Might be related to a Development Gag
If the series runs long enough, the term runs a high probability of becoming either canon or an in-universe nickname.
Films — Animation
- The DC Comics writing staff has a long tradition of referring to Mr. Mxyzptlk as "Bill" to sidestep the issue of how to pronounce his name.
- Mix-zees-pit-lick, according to one book.
- In the animated series, he does a rebus showing it as mix-Yess-spit-lick (blender, band 'Yes' styled logo, tongue doing wet raspberry, tongue licking).
Films — Live-Action
- The animators for The Hunchback of Notre Dame decided to nickname Frollo's horse Snowball. This has caught on with fans, thanks to an audio commentary, and retroactively also became the name of Jafar's horse and the monster pulling Hades' chariot.
- The sequence for the song "Hellfire" was nicknamed "Mr. Frollo's Wild Ride" by the animation team.
- The roach in WALL•E is named Hal.
- While writing the Harry Potter series, J. K. Rowling mentally used the term "The Big Seven" to refer to Harry, Ron, Hermione, Neville, Ginny, Luna, and Draco.
- The Pepperpots (Pythons in old lady drag) in Monty Python's Flying Circus.
- Star Trek, starting with The Next Generation, has "Okudagrams" - the displays on the touchscreens and monitors - after their creator Michael Okuda.
- The engineering access tubes were dubbed "Jeffries tubes", which was a canon name by TNG.
- Irving A. Feinberg was the property master for Star Trek: The Original Series. The little gizmos he came up with for the show (such as the medical scanner and the laser scalpel) were nicknamed "Feinbergers" by the cast and crew. The usage later spread to the fanbase.
- Similarly, the wall panels were often labeled with seemingly nonsensical phrases, like "GNDN435". This actually stood for "Goes Nowhere, Does Nothing", indicating the just-for-looks nature of all the pipes and wires in the Enterprise's interior.
- Caprica-6 from Battlestar Galactica, although that eventually made it into the show dialog as well.
- HRG (Horn-Rimmed Glasses) in "Heroes".
- The concentration face Hiro Nakamura makes in order to travel through time or space is apparently called the "squishy blinky" by the production crew.
- The pterodactyl, Myfanwy, in Torchwood.
- The Barracks on Lost are called "New Otherton" by production, which spread to fans and then incorporated into dialogue as Sawyer's nickname for the place.
- On Stargate SG-1, "kawoosh" was a production nickname used to describe the "unstable vortex" formed when a Stargate opens. The term wasn't used on the show until the episode "Crusade", in which it was coined in-universe by Samantha Carter:
Mitchell: I'm sorry, the what?
Carter: The unstable vortex of a forming wormhole. Kawoosh!
Mitchell: Don't think I've ever heard you call it that before.
Mitchell: Don't get me wrong, it's good.
- In the movie, the stargate had a conical vortex coming out the back of it while active, which was called "the strudel" in one of the featurettes. The strudel was dropped in the TV series.
- Doctor Who:
- On the set of The X-Files, the Scully Box was referred to as the "Gilly-Board", referring to actress Gillian Anderson.
- The RoboCop nickname for John Cable after he become a RoboCop in RoboCop: Prime Directives first came from the production staff. In the series itself, he's either referred to by nis real name or "Crime Prevention Unit 002".
- In Portal, the portal maneuver was called "flinging," and the Aperture Science Material Emancipation Grid was dubbed the "fizzler". The absent character who left behind dens and scrawlings on the walls was named the Rat Man (for his scrounger-in-the-wall habits). Later, he was promoted to a first-order character via an interquel comic book. His real name is Doug Rattman.
- The main character of the Wing Commander series originally had no default name, but the production crew called him Bluehair. He was later given the name Blair* as a nod to this.
- During development, VVVVVV was simply called "V" by its creator Terry Cavanagh.
- Guybrush Threepwood, hero of the Monkey Island franchise, was named Guybrush from the file containing the "guy-brush" the developers used to animate his sprite. It stuck as his name.
- In late 2010 Egosoft announced they were working on a project which they called TNBT, short for The Next Big Thing. In 2011, it was announced as X Rebirth.
- Combining this trope with Theme Naming, most of The Legend of Zelda games produced in the Nintendo 3DS and Wii U generation are internally named after playing cards. The Wind Waker HD is called "King", Ocarina of Time 3D is called "Queen", A Link Between Worlds is called "Jack", and Majora's Mask 3D is called "Joker".
- The unreleased game many fans know as Fallout: Van Buren was never actually planned to be released under that name. It would have been called Fallout 3 had Interplay not gone under, and a proper Fallout 3 didn't come out until Bethesda Softworks revived the franchise in 2008.
- Final Fantasy VII:
- The poor unnamed Redshirt accompanying Cloud, Tifa and Sephiroth and Zack who dies on the bridge in the Nibelheim mountains was affectionately named 'Zako' by Nojima. 'Zako' is a Japanese slang word referring to Mooks and also works as a pun on 'Zack'.
- The Ultimania guide contains concept artworks naming and assigning ages to various characters who are not named or aged in the story. This includes names and ages for Tifa's father (Brian Lockhart, 40) and Cloud's mother (Claudia Strauss - 33 - note also she's got a different surname to her son).
