Jack Bauer's Happy Hour (or The Jack Bauer Power Hour, whichever you prefer) - The show itself. On GameFAQs there was a topic called "The Jack Bauer Power Hour Club" whenever "24" is on.
Rolaide - Lynne Kresge, played by Michelle Forbes, who also played Ensign Ro Laren on Star Trek: TNG.
Black Bauer (or Blackjack) - Curtis, named so for being a field agent nearly on par with the main character Jack Bauer (oh, and he was black). Inspired some other "Bauer" nicknames that were mostly in jest:
The Other White Bauer - Aaron.
Female Bauer - Audrey, for some of her Made of Win moments in season five.
Bald Bauer - Wayne, for teaming up with Jack and being competent once.
Rack Bauer - Renee Walker, who turned into Jack with boobs as the season went on.
Spawn - Kim Bauer (shortened from "Spawn of Kiefer").
Dim - Kim, when she's being particularly... not bright (i.e. pretty much all of Seasons 1 & 2, and much of 3)
Soul Patch - Tony Almeida, cause of his... interesting... facial hair in Season 1.
Some have changed this to Neck Patch, after he was shot in the neck in season three and spent the rest of the season with a large white patch over the wound.
Im-Ho-Terror - Habib Marwan, a.k.a. Arnold Vosloo, a.k.a. The Mummy.
"The SpyFam": "SpyBarbie" for Sydney Bristow, "SpyDaddy" for Papa Wolf Jack Bristow, "SpyMommy" for Magnificent Bitch Irina Derevko, and "SpySkipper" for Nadia Santos.
Irina also got "Mama Hari".
"Arvin Clone", which IIRC, was used in canon, for Joel Grey's character in S4.
"The Sadistic Dentist of Asian Persuasion" for the unnamed Torture Technician in seasons one and two.
The Amazing Race has had so many of these that it is perhaps better not to try and list them all; we'll limit ourselves to regular race terminology and skip over team nicknames. Some originated on the show itself, since the teams often have nicknames for each other, some came from the fandom.
Killer Fatigue - the point when stress starts to take its toll on the racers
Mercy Kill - automatically eliminating a trailing team instead of letting them finish the leg
NELs - short for Non-Elimination Legs
Super Leg - double-length legs which last two episodes
America's Next Top Model:
Tyrant - A nickname for Tyra Banks that expresses many people's opinions of her.
Tyra-ranasaurus Rex says rar!
Tootie Carparts/Shroom - Much-derided Cycle 9 winner Saleisha Stowers was saddled with this first over at Television Without Pity. "Tootie" and "Shroom" both refer to the strange bowl-cut makeover she was given in the cycle. "Carparts" was added because of a photoshoot where she was supposed to represent... car parts.
"Dora" became sort of common around IMDB for a while, in reference to the above mentioned bowl-cut.
Admiral Ro - Admiral Helena Cain, as played by Michelle Forbes, who also played Ensign Ro Laren on Star Trek: TNG.
Gina - The Number Six Cylon who was captured by the Pegasus crew. From the feminized form of GINO, or "Galactica In Name Only" (a criticism leveled at the new series by fans of the original). Ron Moore used the name to refer to the character in podcasts, and when Razor aired, Gina Inviere (Romanian for "resurrection") was given as the character's name.
Blanders - Among certain fans, specifically those stuck in Season Two, the accepted way of referring to Kara Thrace's husband, Sam Anders.
Chip Six - Baltar's imaginary girlfriend, who was at one point thought to be the result of a computer chip implanted in his brain. The theory was disproved, but the nickname lingers on — and was extended to cover his real Cylon ex-girlfriend's hallucinatory "Chip Baltar." (AKA "Head Six", as in the script, but there are just too many jokes that could be made about that one. At least "Six-In-The-Head" has some dignity.)
Buffy the Vampire Banger - The eponymous character, after her relationship with Friendly Neighborhood Vampire Angel heated up. Made even more appropriate during Season Six.
Pencil Boy - The First Evil. So nicknamed due to his intangibility making him useless for anything except monologuing and making scary faces. Or as one fan put it: "What's so scary about this guy? He couldn't even pick up a pencil if I dropped one on the floor."
"Captain Cardboard" - Riley, Buffy's Season 4 boyfriend. Also originally used in the script.
"Smidge" - A mostly British nickname for Sarah Michelle Gellar, whose initials are SMG.
"BAIT" - Bad Actress In Training. Applied to the "potential Slayers" that showed up in Season 7, it apparently came from Buffy message boards (particularly The Bronze). Possibly alluded to in an episode where Kennedy said that she'd "never been the bait before."
"Fanged Four" or "Scourge of Europe" - Darla, Angelus, Drusilla, and Spike. "Fanged Four" is not to be confused with "Fang Gang", above. "Scourge of Europe" was said on the show, but only applied to Angelus.
"Captain Peroxide" - Spike because of his platinum-blond hair.
The Folk Man has become a popular name on Youtube for Caleb.
Big Gay Chris - A Television Without Pity nickname for the very pretty, very femme-acting Mr. Fanservice that made Season Six slightly more entertaining. As it obvious he was a Kid from the Future, and Piper already had one kid, Wyatt, people assumed they were one and the same, leading Wyatt to be occasionally nicknamed Tiny Gay Chris until it turned out Chris was actually Wyatt's younger brother. The baby version of Chris inherited the latter nickname once he was born.
Maggot Neck - Another Television Without Pity nickname for Billie Jenkins. Her neck was... strange, to put it mildly. She was also known as The Retarded Bimbo, due to Kaley Cuoco's inadequate interpretation of the role combined with the character's abundant stupidity, which later became The Ultimate Retard once the character started being ominously referred to as "the Ultimate Power" on the show.
The Dolt - Another TWOP nickname for Leo
The Doormat - For Extreme Doormat Darryl, who ends up being constantly used and abused by the Sisters.
The Funbags - For Phoebe's breasts, particularly since season 5, when Alyssa Milano lost weight.
Hotchalanche - Any moment in which Aaron Hotchner unleashes his awe-inspiring powers of observation, analysis and rhetoric to demolish a serial killer, lawyer, Obstructive Bureaucrat or police officer, in the interest of getting the latest job done.
Liquid Man, the Amazing Bloat, and Good Ol' Soapy - Three cadavers that showcase, in all their gory, various stages of decomposition (namely, liquefied remains, accumulated gases that make a body swell up like a balloon, and saponification.)
GSR. Usually used as shorthand for "gunshot residue", a real forensic test to detect whether someone has fired a gun recently. CSI shippers use it for "Grissom/Sidle Romance".
A rare case of a body part getting a nickname, Nick's short-lived mustache during season 5 was and still is "The porn-stache".
All the CSI franchise shows have fan nicknames for most ships, it would take a whole page to list them all. Most can be found at the Talk CSI forum's Shipper Central section, and yes you can view it without registering.
Ice Cream Girl/Ice Cream Kid: D.B.'s granddaughter, stemming from a mention in the article that announced her appearance of D.B. getting her ice cream.
What do you call specific incarnations of characters played by multiple actors?:
Just about all of the Doctors are called by their place in the numerical order of regenerations. Which format gets used - that is, One, Two, Three or First, Second, Third - depends on preference. The First, Second, Third names tend to be used by the BBC in official material, and the One, Two, Three format is stereotypically associated with post-2005 fans and Estrogen Brigade types (due to the ease of shortening Tennant's Tenth Doctor with the system), but is in fact Older Than They Think and even briefly used in the show itself a couple of times (such as in the Fourth Doctor's skipping rhyme in "Robot", the Image Song "Song for Ten" and the Eleventh Doctor's cracker poem in "Time of the Doctor"). For what it's worth, Colin Baker likes to affectionately refer to his Doctor as "Sixie". And Billie Piper and John Barrowman call David Tennant's Doctor "Ten-inch".
Romana incarnations are referred to with Roman (heh) numerals - Romana I (Mary Tamm), Romana II (Lalla Ward), and Romana III (Juliet Landeau, the Big Finish Romana).
Master incarnations are usually referred to by the name of the actor - Delgado Master, Ainley Master, Simm Master, Macqueen Master etc. - with the exception of the horrible rotting Master who was played by two different actors and so is generally called Crispy Master (or Pratt-Beevers Master).
BillDoc, PatDoc, JonDoc, TomDoc, PeteDoc, ColDoc, and SlyDoc. Then PaulDoc, ChrisDoc, DaveDoc, MattDoc, and PeteDoc II...
Non-canon incarnations, due to not having a numerical placement (or sharing it with a TV Doctor) tend to get named for the story they appear in ("the Shalka Doctor", "the Curse of Fatal Death Doctor"), the actor who portrayed them ("the Joanna Lumley Doctor", "the Nicholas Briggs Doctor") or occasionally just a fun nickname ("the Greenpeace Doctor", for a stage show Doctor who wore a Greenpeace tshirt as his costume). "Dr. Who" is usually referred to as "the Cushing Doctor" just to prevent confusion.
Story types and eras get nicknames too:
"Historical"/"Pure historical" - a story format where they would go back in time and not encounter aliens, save for the time travellers themselves. Sometimes defined as 'no science fiction elements', but some are still science fiction stories in theme, like "The Aztecs" (which is about changing the past). Very much associated with the First Doctor and the show's Early-Installment Weirdness in general, as the only non-Hartnell pure historicals are the Second Doctor's "The Highlanders" and the Fifth Doctor's "The Black Orchid". The first historical was "10,000 BC".
"Pseudohistorical" - they go back in time in Earth's history, and do encounter aliens. "The Time Meddler" is the first one.
"Celebrity historical"/"Celebrity pseudohistorical" - they go back in time, and encounter a famous historical figure. (And/or aliens.) The first Celebrity Historical is "Marco Polo", and the first Celebrity Pseudohistorical is "The King's Demons" (or arguably Charlie Chaplin's cameo in "The Daleks' Master Plan", though he only appears in a Breather Episode that has no science fiction elements in it itself).
"Base Under Siege" - the Doctor lands in a small and isolated base full of interesting people being besieged by something nasty, quite often (though not always) an abstract or nebulous force rather than a specific 'monster'. The trapped people are useless against the force for whatever reason, and the Doctor helps them fend the thing off. The big themes are claustrophobia and guest characters dropping like flies. Associated with the Second Doctor's era, where it was used very heavily as a cheap way of producing horror, but also shows up earlier and later - the First Doctor story "The Tenth Planet", the Fourth Doctor stories "The Ark in Space" and (especially) "Horror of Fang Rock" and the Tenth Doctor episodes "The Impossible Planet" and "The Waters of Mars" fit the formula too. The Eleventh Doctor story "Cold War" is one of these, as an intentional and knowing homage to this story style.
"Gothic" or "Hammer Horror" - story type focusing on a Pastiche of Gothic Horror or Hammer Horror tropes and stories, and Victorian - 1950s pulp literature. Associated with Season 13 and 14 (with the Fourth Doctor) and Philip Hinchcliffe's tenure as producer, though some Gothic stories show up earlier and later than this (stories like "Horror of Fang Rock", "Image of the Fendahl" and "State of Decay" fit, and some people include things like the Third Doctor story "The Daemons" and the Eleventh Doctor's "Hide", again a conscious take on the story style).
"Running down corridors" - generic term for unspectacular Padding sequences of characters running (down corridors), escaping from prison and getting captured again by the same people, or generally doing something pointless intended to give the illusion of action and plot advancement rather than actually being action. Especially if it happens in the third episode of a four-part story. Example use: "The concept of "Frontier in Space" is good but there's so much running down corridors."
"Russell T Davies' Gay Agenda" - Sarcastic reference to various bits of the fandom's objections to what they perceive to be a high level of homosexual/bisexual characters in the new series.
Showrunners seem to attract nicknames.
"JNT" - The late John Nathan-Turner, executive producer in the 1980s. Among those more critical of his tenure, "John Satan Turner" is sometimes heard.
"RTD", "Rusty", "Uncle Rusty", "Russell T" - Russell T Davies, former executive producer. Or even occasionally RTDOBE, after he was awarded Order of the British Empire.
"The Grand Moff", "TGM" or "The Moff" - Steven Moffat, current executive producer. The latter is currently more popular in a poll on The Doctor Who Forum. According to Karen Gillan in Doctor Who Magazine, Steven himself is trying to get "The Mofferator" to catch on. "Lord Steven of Moffat" has also been spotted. DWO Whocast and Staggering Stories Podcast use "Vast Toffee" an anagram of his name missing out two letters (MN, deemed to stand (clutching at straws) for "Master of Nightmares".)
Creator/Terrance Dicks, 70s script editor and modern day elder statesman, is often called "Uncle Terrance", even by new series writers. Also "Uncle Tewwance" thanks to his weak R.
"Handy Doctor", "Handy", or, more crudely, "The Handjob" or "Dildo Doctor" — The half-human Doctor clone created from the Tenth Doctor's severed hand in "Journey's End". Also called "Doctor Blue"; "10 2.0", "10.5", TenII and TenToo; Proper Doctor and Other Doctor (referring, in that order, to the "real" Doctor and the half-human Doctor), taken from Proper Dave and Other Dave from the two-parter "Silence in the Library"/"Forest of the Dead"; or "Cloen", a misspelling of "clone".
"Doctor Cullen" — the Eleventh Doctor, played by Matt Smith, as an early promo pic showed him dressed and posed like Robert Pattinson a.k.a. Edward Cullen from Twilight. Also known as "Sparkle!Doctor". People abruptly stopped using this nickname once his very un-Twilight performance started, though. Other nicknames for the Eleventh Doctor: "Eleventy", "Raggedy", "Poncho Boy", "Flop-Haired Wuss", "Baby Doctor".
"The Dalek Fucker" — early nickname for Peter Capaldi's Doctor based on role association with Malcolm Tucker.
"Dalek Fred" — the Dalek who shot the Doctor at the end of "The Stolen Earth" (based on the way the Cult of Skaro name themselves).
"Fred" is also used for another Dalek — the Dalek Ian traps in a hole in "The Chase", thanks to him Waxing Lyrical to make a Bond One-Liner referencing the novelty song "Right, Said Fred".
The Fungoids in "The Chase" are called Fungoid Fred, Toadstool Taffy and Mushroom Malone. These were names given to them by the production team.
"Flying Killer Time Monkeys" — The bat-like creatures unleashed in "Father's Day", officially (if not on-screen) called "Reapers". "Time monkeys!" briefly became a popular way to answer questions of the form "Why can't the Doctor just go back in time and..."
Puddle — as in a small Pond — the then-unidentified child of Amy Pond. River Song/Melody Pond
"Cybusmen/Cybusman" to denote the Cybermen made by Cybus Industries rather than Mondas.
Team Hipster — The Eleventh Doctor, Amy and Rory. Mostly due to Matt Smith and Arthur Darvill's tendency towards ridiculous sweaters and skinny jeans, while Karen Gillan can look like a redheaded Twiggy at times.
Team TARDIS — The Twelfth Doctor, Clara and Danny. The actor playing Danny started using it a lot when talking to fans and they picked up on it.
"Assistants" — Classic series media misnomer for what most of the fandom calls a "companion". It's not considered totally incorrect, but usually marks the person using it as someone who was a fan of the show in the 1970s (like when Malcolm Tucker from The Thick of It suggests a tabloid journalist publish pictures of "Dr. Who's assistant in a school uniform"). Some of the actors use it too, such as Jon Pertwee and Tom Baker. Seems especially associated with the main female '70s companions — Liz, Jo, Sarah Jane, Leela, Romana.
Wilderness Years — The period between the end of the classic series (1989) and the beginning of the new series (2005)
"Vwoorp! Vwoorp!" seems to be pretty universally agreed upon by fans as the way to write the sound the TARDIS makes when it takes off and lands. It originated as the sound effect in the Doctor Who Magazine comic strips, although many of the fans who use it now probably don't know the source.
"The Whomobile" — The more extravagant car used by the Third Doctor for a couple serials, used by producers as well as fans. Not to be confused with his more ordinary car, Bessie.
"Jesus-Doctor" — General term for the Messianic Archetype symbolism applied to the Tenth Doctor in many stories.
"Reverse the polarity of the _____" — whenever the Doctor just kind of fixes a thing by pointing his sonic screwdriver at it or by pulling some switches, and it's glossed over as to how (e.g. "At the end of "Love and Monsters" the Doctor reverses the polarity of the concrete"). From the third Doctor's imaginedCatch Phrase "reverse the polarity of the neutron flow".
"Pineapple Hair" — The spiky hair-do◊ Martha has for a lot of her appearances.
"The Plaything of Sutekh" — the disembodied hand (belonging to a stagehand who didn't realise they were on camera) that is briefly visible when Sutekh gets up from his throne in "Pyramids of Mars".
"Leather bikini" — Leela's outfit, notable because it's not really a bikini.
"Cult of Rose" — Derogatory name for obsessive fans of Rose who deny that any companion before or since has contributed anything significant. Also known as "Cult of Skarose" after the Cult of Skaro, the only remaining Daleks in the universe during the period between "Doomsday" and "Evolution of the Daleks". It seems to have evolved into referring to people who obsessively try to get Rose and the Doctor together and call Rose the perfect companion. It seems to have started here, here, or here.
"Hand Porn" — Can refer either to all the times the Doctor and Rose held hands, or Fetish Fuel involving the Tenth Doctor's severed hand.
"No hanky-panky in the TARDIS" — the Classic series' No Hugging, No Kissing rule. Taken from a phrase used by John Nathan-Turner, who had to contend with the resultant UST of a Doctor and companion pair who were publicly dating (and married soon after she left the series) and then a Doctor surrounded by attractive teenagers, for whom his first rule was to ban him from touching any of the women.
Downton Abbey: The show itself gained the nickname "Hound's Bum," due to the very first scene in the intro being a shot from behind of the family dog walking toward the house. Either encouraged or outright created by star Dan Stevens.
Thomas Barrow also gained the title "Edwardian Sex Pest."
Dead Bob - The ghost of Cst. Benton Fraser's father, Sgt. Robert "Bob" Fraser, who is killed in the show's pilot but manages to become a recurring character anyway. Also called "Fraser Senior" or "OFDM" ("Our Favourite Dead Mountie").
OFM - "Our Favourite Mountie" is, of course, Constable Benton Fraser.
OFC, "Our Favorite Cop" is either of the Rays.
The Riv-Ray V's Buick Riviera.
The Goat-Ray K's Pontiac GTO.
Stetson of Invincibility-Fraser's hat, referring to a running joke that it has magical powers to protect him from harm.
The main fanfiction archive is still sometimes referred to as "Ex-wood" even today, because it was first hosted on the Hexwood forum before moving to its current squidge.org location.
With characters including 'Dirty' Den Watts, 'Nasty' Nick Cotton, Big and Little Mo Harris and Slater, Squeal Beale and 'Mad' May Wright.
EWTN: Rita Antoinette Rizzo aka Mother Mary Angelica of the Annunciation, founder and host of EWTN: "The Immortal Nun", because of her longevity and how the reruns of her talk show make people often believe she's still at the helm or her show's still on. (Even when, due to her old age and ailing health, her show went off the air in 2001).
MoyaJohn/TalynJohn - Used to differentiate between the two Crichtons in season 3.
Most of the episodes are referred to by acronym, i.e. "Through the Looking Glass" is "TTLG"
FS - The show
"Black Tee Episode" refers to any episode in which the crew's sanity takes a severe hit. Possibly began with "Back and Back and Back to the Future" where John wore a black t-shirt as he experienced time skips. The creators tended to have John's wardrobe include a black t-shirt when it was one of those episodes. Epitomized by "Crackers Don't Matter".
YoSaffBridge - The Femme Fatale who appears in two episodes and never reveals her real name. This name is portmanteau of the three aliases she uses.
Forever Knight: Has nicknames for ships and fans of various characters that would take a whole page to fill. For example, 'Knighties' are either fans of the show in general or specifically Nick fans. NNPack is used for fans of the Nick/Nat ship. LaCroix fans are Cousins. (LaCroix is often referred to as 'Uncle' by them). Originated at FORKNI-L, though it's spread a bit.
The show itself is often called the Mob Power Hour due to the increasing shift to the mob instead of the hospital.
Let's not even get started on Spinelli's very own nicknames for people, such as "Maximista" for Maxie and "Stone Cold" for Jason. He refers to himself as either "The Jackal" or "Grasshopper"
Some of the fan nicknames for characters/writers:
Robert Guza Jr, the head writer, is often called "Luza" to show displeasure with his writing.
Spinelli is called "The Spaz" or "Spaznelli" by people on soap boards.
Winifred is called Winnewack or "That stalker chick" or "Spin Clone" by militant Spixie fans
Maxie, on the other hand, is still called "The Bad Blonde One" (what Spinelli used to call her) by anti-Maxie and anti-Spixie fans. Unfortunately, Winifred's nickname for her, "Minimista", never caught on.
The Non-Judging Breakfast Club - Blair, Serena, Chuck and Nate. Arguable case, as it was coined by the show. However it's only been said once, by Blair, yet online the Non-Judging Breakfast Club (or NJBC for short) is the official name for anything regarding the friendships between these four.
Granderbilt - William Vanderbilt (Nate's grandfather)
E. Fish - Elizabeth Fisher
The van der Basses - the van der Woodsens and Basses after Lily and Bart got married in season one.
Evil Uncle Jack - Jack Bass
Chuck Bass also went by the Fan Nickname Rapey during most of season one.
ikiN - Jessica, Niki's "mirror self". Named by Television Without Pity before Jessica's name was revealed. This caught on so well that most members of the forum refuse to call her Jessica, and still use ikiN.
Lady Taskmaster - Monica, as her power (the ability to mimic what she sees perfectly) is the same as the Marvel character Taskmaster.
Peter Pan - for Claire's Season 2 boyfriend, West. Not only for his ability to float-fly, but for his astounding immaturity which even leaks onto Claire. (His idea of using their powers for good? To play a traumatizing prank on a mean cheerleader.)
HRG - Noah Bennet. Stands for "Horn-Rimmed Glasses," still occasionally used for Noah in his Company role. The fact that his real name was unknown for most of the first season encouraged its use and helped it stick.
Mystery Sock - Isaac Mendez, named after how Hiro Nakamura (whose native language is Japanese) pronounces "Mister Isaac".
Mo, Momo, HoMo, Mohinderance, D'ohinder - Mohinder. The latter two refer to the times when Mohinder clings to an Idiot Ball.

MohinderFly, Spider-Mohinder, Spider-Hindu, MohinderBrundleFly, BrundleMo - After Mohinder injects himself with Super Serum in season 3 to give himself powers, he starts undergoing side effects similar to Seth Brundle from The Fly. Also he sorta goes crazy and captures random test subjects and glues them to the wall of his lab in some sorta webby substance.
Mommy Mohinder - When Matt and Mohinder were taking care of Molly.
Papa Petrelli - Arthur Petrelli, Peter and Nathan's father and Big Bad of season 3.
Senator Skyboy- Nathan.
Copycat, Deus Ex Peter - Peter.
Sythan - After the events of Volume 4 which had Parkman trap Sylar's mind inside Nathan's dead body.
Flamepalm - Meredith who feels the need to show off her fire powers by opening her hand and releasing a flame in her palm in every appearance she makes in season 3.
This soap with such simplistic characterization and an emphasis on appearance over acting talent when casting, making it easy to define many of the characters by a single arc, personality trait or physical resemblance among those watching the soap as a Guilty Pleasure.
Dame Devine - Clare, revered by the snarkier devotees of Hollyoaks because she totally owned Warren so many times, tried to kill Katy, and always had great one-liners.
Cuntstable Boringtine - Calvin. The Valentines were collectively dubbed "The Boringtines", being dull and entirely superluous to the show beyond a Token Minority family, but Calvin is the least interesting of a boring bunch.
My Bloody Valentine - Lauren, yet another member of the Valentine family who, appropriately enough, is a Perky Goth.
Fembot/Rapebot - Katy, portrayed by an actress so bad (even by Hollyoaks standards) that her attempts at emoting appeared robotic.
Also "Chief Storyliner Tointon", after fans noted her uneven and inexplicable presence in most characters' plots and forming unlikely out-of-character friendships (especially so with John-Paul) and romantic pairings (Zak) in a Writer on Board sort of way, snarkily implying that she had some influence on the show's scripting merely to give herself extra scenes.
Mr Happy and The Angry Troll - Jake and Nancy, inspired by an in-show comment from Mercedes.
Birdseye Kid - Tom, the irritating Soap Awards-bait child who bears a striking resemblance to the kid from the Birdseye fish fingers commercials.
Rubbish Tranny - Kris
Speak 'n' Spell - Sasha, another valentine whose voice sounds flat, unemotional and somewhat robotic.
Teenwolf - Gilly
Easter Island - Warren, an unintentionally unlikeable character (despite the writers' unrealistic expectation that viewers should cheer for him) whose head resembles the famous stone statues of the aforementioned Polynesian island.
Also "Angry Pederast", for his questionable Ho Yay-filled capricious friendship with an 18-year-old Justin.
crash!mum - The mother of the Valentine family, who existed pretty much entirely to get run over as soon as they arrived and thus inspire bucketloads of tedious and poorly-acted angst.
crash!rape - a phenomenon where rape is unexpectedly featured in a plot to advance an arc (although fortunately not played for laughs). This happens surprisingly often. It was inspired by a fanfic where Jess was raped in a throwaway sentence.
The Mandy Richardson University Of Chester - Hollyoaks Community College, which runs every course from law to teacher training, fashion to film-making.
Pouty Founty - The fountain in the village where many angsty scenes take place.
Moriarty - the unidentified guy who shoots House and tells him he sucks in his imagination for an entire episode but in reality escaped before he could be caught or his real motives could be revealed; named after Sherlock Holmes' Arch-Enemy.
Lucas is known within the House/Wilson areas of the fandom as Mr. Sprinkles due to the Ice Cream van he drove around in during one of his first appearances.
Cut-throat Bitch/CTB: Coined by House in the show, refers to Amber, Wilson's girlfriend in season 4.
iCarly: iSeddie - Title of the 2nd part of season 4's episodes after iOMG (excluding iParty with Victorious as per production order) due to Sam and Freddie being a couple in all episodes of this part of season 4, the title given by those who don't ship the Seddie ship. Mostly called a spinoff to the original due to all characters being out of character.
Helen Pikachu - Contestant Helen Lyu, for kinda looking like a certain electric mouse. She was also given the nickname "Ană da China" ("Chinese Dwarf"), for being pretty short and looking Asian.
Marcchan - Affectionate nickname for contestant Marcos Paulo, given by a deviantART user. It appears to be pronounced as "Markan".
Sertanejo ("Country Guy")/Zezé - Contestant Marcos Duarte, for singing country songs most of the time he was in the competition. The second one is because of the fact that he sounds like Brazillian country singer Zezé di Camargo. Also, the first one is occasionally combined with "Nojo" (meaning "Disgust"), making the portmanteau "Sertanojo" ("Disgusting Country Guy").
Priscilăo - Contestant Priscila Borges, for some reason.
Badass Shotgun Guy - Prior to the announcement of Kabuto, pictures surfaced of an unknown man holding a shotgun, who was reported to be the lead actor for the 2006 series. He is a minor legend in the fandom and each year fans express their hope for him to appear at last.
Showa Era and Heisei Era - Fan designations for classic series in the 70s and 80s and post-revival series from the 2000s on, respectively; named for the Japanese eras they primarily took place in. The dividing line is that the Showa series had creator Shotaro Ishinomori's involvement (some TV movies made shortly into Japan's Heisei era are considered part of the franchise's Showa group because of this).
Neo-Heisei Era - A further subdivision applied to Heisei series coming after Kamen Rider Decade; due to a shift in production staff, tone, airing schedule, and other things.
Rocket Man - Fourze, because of his space travel-themed appearance
Kamen Rider Onigiri - Also Fourze, whose helmet resembles an onigiri to some fans
Ankh Tsuchiya - Idol Singer Anna Tsuchiya, who performs the show's theme song. So-called because some fans thought that in the official music video her hairstyle resembled Ankh from the previous series.
Kamen Rider Glee - The show, due to its high school setting and an episode in which Yuki assists the school's glee club.
Kamen Rider Bruce Lee -Kamen Rider Meteor, due to his Jeet Kwon Do style, and his fond use of Kiai noises.
Kamen Rider Pikachu - What the fans have been calling Meteor's Super Mode Meteor Storm.
D.A. Barbie - ADA Serena Southerlyn , so named because because for the first season or so of Elisabeth Rohm's tenure, Southerlyn did little than stand around and look pretty.
Repeat Offender - an actor or actress who has appeared on one or more of the shows in multiple roles. Includes S. Epatha Merkerson (first appeared as a victim's mother), Jerry Orbach (a defense attorney with Lenny's trademark accent markedly missing), Diane Neal (a rapist), and Courtney B. Vance (a murder defendant).
Texas Termanatrix - ADA Abbie Carmichael, so named for her no-nonsense, no-mercy attitude.
The Mothership - The subtitle-less original. Use to avoid confusion between it, SVU, and CI.
Un-Stabler/In-Stabler - Det. Eliot Stabler from SVU due to his frequent Rabid Cop moments.
St. Olivia - Olivia Benson
Also "Oliska" for the perceived blurring of the character and the actress, Mariska Hargitay.
"Butchy McFabulous" - Oliska's polar opposite. Seen most prominently in Seasons 3 and 4. Made of awesome.
The Wonder Chins - Stabler and partner Det. Olivia Benson. Guess why.
Glasses of Justice - The glasses ADA Alex Cabot would occasionally wear.
There are a whole host of funny TWOP nicknames explained here.
The Lone Ranger: The Mexican fandom of the series calls the titular character as El Llanero Con Solitaria which is translated from Spanish as The Worm-Infested Ranger, by playing with the phonetics of his Spanish name, El Llanero Solitario.
Darlton - Used for the showrunners, Damon Lindelof and Carlton Cuse. They have jokingly claimed to prefer Cuselof.
Fenry - When the character who had been calling himself "Henry Gale" turned out to be lying about this (and pretty much everything else), fans nicknamed him "Fenry", short for "Fake Henry". When we finally found out that his real name was Ben at the beginning of Season 3, some people started to call him "Benry" instead.
Losties - The stranded passengers.
This has led to the creation of other names for groups, such as the Tailies (tail section of the plane) and Freighties/Boaties (from the freighter).
The Hydra - Television Without Pity nickname for showrunners Carlton Cuse and Damon Lindelof (a reference to the Hydra Station, a prominent location in the beginnning of season 3).
Esau - Jacob's mysterious rival, after Jacob's brother from The Bible.
Also affectionately referred to as MIB/Man In Black, Smokey, or The Nemesis
Craphole Island — The island. Coined by Shannon, picked up by the fandom.
Flocke - Fake Locke i.e. Esau/smoke monster disguised as Locke
He's been getting tons of nicknames: UnLocke, Smocke, John Mocke and the Lockeness Monster
Smokey/Smokey the Bear- the Smoke Monster. The first is self-explanatory. The second came from some theory that the smoke and the polar bear were created by the same force or were in fact the same entity.
Sayisus: Certain fan circles use this for Sayid, as a portmanteau of Sayid and Jesus, in reference to Sayid's resurrection at the beginning of season 6.
Princess Faraday: Also used in certain circles for Daniel Faraday. It's very popular on ontd_lost, for instance.
Mad Men: After Joan surprised him in bed, her fiance Greg decided that she was just a bit too slutty and took her down a peg or two in Don's office after hours, earning him the nickname Dr. Rape. Or Dr. McRapey.
M*A*S*H: "The Alan Alda Show"; particularly when Alda became one of the driving creative forces behind the show by the sixth season.
Spoony or Spoonface - Katya Kinski, based on the absurd suggestion that she looks like a big shiny spoon. After seeing enough MS paint art on the subject, you almost start to see the resemblance...
BSW - Blue Speedo Will, after his especially revealing credits shot. This is considered by some his only worthwhile contribution to the series.
Will 2.0, Williver, or just plain Will - Oliver, the Jonas Quinn brother of Will, who materialised from nowhere when the original actor quit. Still in use, even though Oliver's tenure is four times the length of Will's already.
The Big Brother House - Number 30, and the vapid twentysomethings who invaded it in late 2006. Actually used on-screen when the inhabitants held a reality TV-style contest ripped wholesale from, er... Survivor.
When referring to Boyd during his last year, recappers tended to just choose their favourite expletive and use it as a proper noun.
Scott Ross, the amoral, sexually indiscriminate biker, was known to many fans as "Scott Ross, that ho" altogether, as though it were a title.
Chris Keller became known as 'Serial Keller' after he revealed that he was, in fact, a serial killer.
Parks and Recreation: Human Disaster - Ben Wyatt. This was one of several insulting nicknames Joan Callamezzo gave him in the episode "Media Blitz". Apparently, people liked it. It's generally used by fangirls who find him Adorkable.
Jeebus - Breakout Character Tommy Oliver, due to his longevity and Deus ex Machina-like powers. Comes with jokes about sacrificing Zords, Pink Ranger fetishes, and more.
Kalishplosions - Starting with SPD, dramatic pyrotechnics became more and more frequent (at one point caused by a jet-spray of water). Then-new executive producer Bruce Kalish was blamed, but there's now evidence that longtime stunt choreographer, Koichi Sakamoto, is the actual culprit... The RPM equivalent (since Kalish left the job after the previous season) is "Ziggysplosion", after Ziggy's Lampshade Hanging of them in "Ranger Blue".
Zordon Era - The series from Mighty Morphin' Power Rangers to Power Rangers in Space. Similarly, "Saban Era" for Mighty Morphin through Time Force and "Disney Era" for Wild Force through RPM, based on which company produced the show. Series after RPM, when Saban took the rights back, don't have a standardized nickname yet; "Post-Disney Era" and "Neo-Saban Era" are common ones.
Koichi Camp - The six-week session of martial arts and stunt training all the actors go through before filming begins. Named after stunt coordinator Koichi Sakamoto, even the more athletic actors have claimed to have been humbled by the experience.
Mighty Morphin' Power Rangers: Zyu2 - Refers to the action scenes that Toei's film crew produced specifically for Power Rangers that were used for the final episodes of Season 1 (following "Doomsday") and the early episodes of Season 2 (before the departure of the Green Ranger and the switch to Gosei Sentai Dairanger footage for all the giant robot battle).
Battle Thong - The Battlizer armor which, in its first, more agile form, resembled little more than shoulder pads, a sword, and a jock strap. Also sometimes called the "Jack Strap" due to its primary user's name, or "cyber diaper."
Tinkersam - Sam the Omega Ranger from SPD, due to his infamously bad condition of being stuck as a ball of light.
iMack - Mack Hartford, given that he's an android.
Retro Rangers - The team recruited by the Sentinel Knight for the 15th anniversary Reunion Show. Coined by actor Johnny Yong Bosch on Rangerboard, when he confirmed that his character, season 2-5's Adam, was the de facto leader of the group.
Power Rangers New Powers - The nameless-in-Power-Rangers core Gosei Sentai Dairanger suits, as popularized by this fan video mocking both the sloppy justification for their sudden existence in Power Rangers canon and the overuse of the words "new powers" during the first usage in "Earth Fights Back".
Power Rangers Blitz - The nameless-in-Power-Rangers and completely unexplained Hikari Sentai Maskman suits; derived from Gia declaring "Legendary Ranger Blitz!" before morphing into "Yellow Mask" in "Samurai Surprise".
Der Preis ist heiß (German counterpart of The Price Is Right): Alter Schreihals (Old squaller), for Walter Freiwald who indeed has No Indoor Voice. Part of his job, I guess.
Pretty Guardian Sailor Moon: Dark Sailor Mercury is referred to as "Darkury" by fans. Some fans also refer to her civilian form as "Akumi" a combination of Ami and Aku meaning dark. Rumor has it the latter was actually coined by the show's staff.
The Price Is Right: The inhabitants of Golden-Road.net refer to the show's pricing games with embarrassingly cutesy pet nicknames like "Cliffy" for Cliffhangers, "Baggy" for It's In The Bag, and so on.
Quantum Leap: GTFW - the mysterious force which makes Sam leap: God/Time/Fate/Whatever.

The Sarah Connor Chronicles: Taminator - Cameron, the cute, waifish Terminator played by Summer Glau. Named after River Tam, the cute, waifish killing machine Glau played on Firefly. There is also "Glauminator" and "Toaster-Cam". There are other variations, such as "Robo-River" and "Caminator." Or even Rivernator. There's also "Cameriver Glau" or the like that pops up from time to time. As well as "Tin Miss" as a reference to the Tin Man from Wizard of Oz.
Sex and the City: After wedding-planner/Pet Homosexual Anthony addressed Charlotte with the cutesy nickname "Char", recappers thereafter dubbed the remaining characters with similar shortenings: Car, Mir, and Sam.
"Moftiss" (or "Mofftiss") has become popular as a portmanteau for the show's two creators, Steven Moffat and Mark Gatiss. (As in, "Moftiss are evil trolls!" or "No, please don't, Moftiss, we can't take it!!")
The purple shirt occasionally worn by Sherlock on the show has been dubbed "The Purple Shirt of Sex". Sherlock's blue scarf is notorious enough that it need only be referred to as "The Scarf". This is also true of John's oatmeal cable-knit jumper, known only as "The Jumper". Yes, Scarf/Jumper is one of the biggest ships in the fandom.
The Pink - Largely retired, but Lana used to wear a lot of pink.
The Squirrel - Lana. Originated because she used to make squirelly faces when getting angry, confused or upset, stuck around because she stole men's nuts. Yes, it's from Television Without Pity.
Nois - As in "no is (is not) [Lois]", used by those who feel she is not worthy of being Iconic Lois Lane.
The Magnificent Bastard - Lionel Luthor. This Fan Nickname has also become a trope name on this Wiki. Also referred to as the MB and The Magnificent You-Know-What. After his possession by Jor-El, he was often referred to as Lion-El.
Chloogle and more recently Lanapedia - Obviously, Chloe Sullivan and Lana Lang, due to the abilities that both have displayed to be able to look up information on just about anything for Clark. Due to some recent developments, the first moniker isn't that far off from canon.
Chucknician - Chuck, who was called Canadian Technician Guy until he was officially named on the show. He was named Chuck in show but that's because he's called Chuck.
Recliner of Doom - the control chair, because it is used only when the city is under attack. The name also possibly comes from the common Atlantis fanfic trope that the control chair will one day do permanent damage to Sheppard's brain.
Tey-Lo - Teyla, who vaguely resembles Jennifer Lopez.
Yahoo - John Sheppard, due to his status as the all American gung ho poster boy.
Angry Puppy - Ronon Dex. Coined in the LiveJournal episode recapping community "Zero Point Snark".
Colonel Skinner - Colonel Caldwell. So called because his actor played Assistant Director Skinner on The X-Files.
RADAR's an alternate name for him, because before his character was officially given a name, the actor decided to take on some of Radar O'Reilly from M* A* S* H's character traits.
Replicarter - The Replicator copy of Samantha Carter.
Ancient Head-Suckers - the Ancient Repositories of Knowledge, because they encase the head of whoever ventures near enough.
Col. Fanboy - Col. Mitchell.
Arm!Porn - a term used in Stargate forums to refer to the tendency, especially in later seasons, to place buff and mostly-buff characters in sleeveless shirts. Since by 9th season, this included every male member of SG-1...yeah...#
Fargate - used to describe the last two seasons, when Ben Browder and Claudia Black of Farscape had joined the cast as regulars.
"CSP" was used a few times when William B. Davis of The X-Files showed up in season 9: the definition given was "Cigarette-Smoking Prior".
Vanessa James has thus far mainly been Fanservice, if occasionally self-aware Fanservice. Her fan nicknames tend towards things like "2nd Lt. Tits McGee".
GateFail2009 (or just GateFail) to refer to the whole series, resulting from die-hard fans upset about the lack of previously known characters, consistent mythology within the Stargate franchise, or the Soap OperaIN SPACE! nature of the series as opposed to the sci-fi adventure format of SG1 and SGA. As well as feminists complaining about...feministy stuff. And, lest we forget, Battlegate Voyager 90210.
"Smurfs" is a commonly used name for the blue, catfish-like aliens hunting the Destiny
Sergeant Greer's early apparent temper problems caused him to be referred to as Furious George.
Nero's time meddling - same concept as the Retroactive Cannon (ie. a force that erases things out of existance in a reboot), only strictly applied to Star Trek.
38-of-D - Seven of Nine from Star Trek: Voyager. Refers to her most immediately striking physical feature, and no, we don't mean her Borg cybernetics. Variants include 2-of-2, 2x2 ("two by two"), and 10-of-10.
Also 6-of-9, when fans thought the new character would be Star Trek's long-promised gay character.
In Italy, the name Seven of Nine is translated literally as "Sette di Nove", so Italian fans started calling the character "Tette di Nove", meaning "Tits of Nine".
Also Barbie Borg after her resemblance to the well endowed doll.
And of course there's Cyber-Tits because of her...well.
Captain Hepburn - Captain Kathryn Janeway (played by Kate Mulgrew) of Voyager, who looked and sounded a lot like Katherine Hepburn and was similar in attitude to a lot of Hepburn's characters. AKA Captain Kate.
Mrs. Columbo, Captain Columbo, in reference to Mulgrew playing Columbo's elusive wife in a spinoff of Columbo.
A number of nicknames originally coined by Chuck Sonnenberg on his show SF Debris have been adopted by certain fan communities:
Captain Mom, once again for Captain Janeway. Originally coined derisively towards the way Janeway micromanages various aspects of her ship, many fans use it positively to refer to her as the crew's matriarchal, warm leader.
The Good Shepherd, yet again referring to Captain Janeway, from the episode of the same name.
Janeway of Borg, referring to Janeway's tendency to pick up and "assimilate" alien crew members.
Captain Bipolar, mostly because midway through the third season, Janeway's command style changed without warning between episodes, due to inconsistent characterization.
And then, there's the Voyager itself: known primarily for resetting everything to status quo at the end of each episode, the ship became known as the HMS Reset Button. Janeway's My Way or the Highway attitude she often cops provides the HMS.
The Magic Meeting Room, and The Magic Conference Table, referring to the room and the prop where major characters gather to discuss the Problem of the Week and its solution. Particularly notable in the episode Twisted, where, in the absence of one, they gather a bunch of serving tables into an impromptu Magic Conference Table.
Duchess, referring to Captain Archer of Enterprise due to his apparent mental instability that could easily lead to his insisting on being called such. Typically applied by noting some big role Archer played in getting the crew into their current predicament, followed by "Nice going, Duchess!"
Strangely, this may have jumped into a completely unrelated series, where the character secret agent Sterling Archer's codename is "Duchess."
The mysterious "Humanoid Figure" who gives Silik his orders in the Temporal Cold War was dubbed "Future Guy" by him (seriously how many fannames has this guy come up with?). This name then became the fans name for the character before it became so popular that by the end of Enterprise's second season producers Rick Berman and Brannon Braga were also referring to him as Future Guy in interviews, as did Paramount's press release for "The Expanse". According to his review of Broken Bow (at least video version) he thinks that the sad part about the whole thing is that the name is derived from sarcasm.
B&B, Bermaga, Beavis & Butthead - The Rick Berman/Bannon Braga writing team, most often seen on the later Star Trek series. This particular pairing has been accused of running the Trek franchise into the ground by a large portion of the fanbase. "Bermaga" is another Television Without Pity name. "Bregma" (rhymes with...) has also made the rounds.
So has "The Blunder Twins."
The killer Bs was popular on some sites for a while.
Captain Quantum - Captain Archer, of Star Trek: Enterprise; played by Scott Bakula, who also played Sam Beckett on Quantum Leap. Scott Bakula himself gave his character the non-cannon middle name "Beckett."
The Winchesters: Due to the parallel between the two sets of brothers, Television Without Pity have dubbed the Winchesters "The Hardy Boys." This was actually used in "A Very Supernatural Christmas" and "Abandon All Hope."
Dean: El Deano or Dashing El Deano, from Television Without Pity. Ducky Lips - A.K.A Dean's pouty mouth. Also from Television Without Pity. Li'l Stumpy, referring to his bowlegs and his lack of height in comparison to Sam. First started on... guess where.
Sam: Sasquatch, Moose, Gigantor, Sam the Ginormotron, Winchester Jumbo-Size, Giraffe, Jolly Green Giant, all referring to his height; Puppy; Darling Sammy (from Television Without Pity); RoboSam (Sam without a soul in season 6), Boy King Sam
John: Daddy Shut Up/Shut Up Daddy — A nickname applied to John on Television Without Pity, who has taken a lot of heat across the forums and in the recaps for his actions (or non-actions) and the consequences of those on the show. Also 'Papa Winchester'.
Castiel: Cas; Clairestiel, when he possesses Jimmy Novak's daughter Claire's body; Thingstiel (Castiel's celestial form); Godstiel (after Castiel declared himself God)
The Impala: "The Metallicar", note Trope Namer for Metallicar Syndrome named in part for the type of music that is often played on its stereo. Also from Television Without Pity, but it's even been picked up by TV Guide.
Alastair: Fake Brando. A Television Without Pity-coined nickname for Hell's main torturer demon in Season 4, who, no matter what host he is in, always sounds like he's doing an incredibly horrible Marlon Brando impression.
Eric Kripke: The Kripkeeper, the show's creator, on whom the fans blame all of their issues and angst.
Lucifer: Lucy; Samifer — Lucifer in Sam's body; Markifer — Lucifer in Nick's body (named for actor Mark Pellegrino)
Other: When Sam merged with the Impala in "Changing Channels", fans dubbed it the "Sampala". Dean, Sam, and Castiel are known collectively as Team Free Will.
Forehead - Gunpei (Go-on Black) from Go-Onger, due to his massive forehead.
Piper - Kegalesia from the same series, due to her costume and the... colorful (porn) history of her actress. When she combined with Bomper in the Net movie specials, the warped combination was named "PipeBom".
Pimp Hikaru - Hikaru (Magishine) from Magiranger with his gold-and-blue ensemble and ability to seduce women, including Makito's love interest while Makito is there.
Aibaranger - Ryunosuke (Shinken Blue) from Shinkenger. A reference to the popularity of his actor, Aiba Hiroki (and his fangirls who invaded the fandom after he was cast in the part), and the title of past series Abaranger.
Ryunosuke is occasionally given the nickname Marijuana Man as well, due to the fact that people unfamiliar with kanji may assume that his helmet's visor looks like a cannabis leaf◊.
Let's be fair though. That visor has been heavily stylized so he'll be able to see out of it. The kanji for water looks more like this.◊ Even if you are familiar with kanji, it still looks a little funny.
Elvis Mode - The Shinkengers' power-up, which looks like this.
Neko-Tono - Shinkenger's Takeru, in reference to an episode where his soul is transferred into a statue of a lucky "beckoning" cat.
Hyde Quinto - Hyde/GoseiBlue from Goseiger, so-called by some fans who think his actor bears a resemblance to Zachary Quinto.
Gumball Machines - The Goseigers' Super Tenswords◊, as seen in this picture.
Sixth Ranger Syndrome - The way most series tend to sideline the Sixth Ranger: leaving him out of battles, sending him off on separate missions from the others, excluding him from team-bonding moments or having him be unable to fight at a crucial moment
Vs. Hair - The new hairstyles that characters are often seen with when they return for the Vs. movie with the following series.
Michael Joe Takeru - Takeru/Red Mask from Hikari Sentai Maskman, to avoid confusion with the Takeru of Shinkenger. "Michael Joe" was the Dub Name Change given to Maskman!Takeru in the Philippines.
AmeriBasco - Basco's potential future Power Rangers counterpart. It is mainly used when talking about how Basco's actor Kei Hosogai could also play the American version of Basco, as he is fluent in English and lived in America for 15 years.
Orange Arms - Akira Nijino from Tokkyuger, who's an Orange Ranger popular with some fans for regularly having his arms on show. A pun on Orange Arms mode from Kamen Rider Gaim (which aired opposite Tokkyuger.)
Survivor (As with Amazing Race, we'll skip player nicknames in favor of game terms only.)
Pagonging - After two tribes merge into one, an alliance of one former tribe's members systematically votes out the rival alliance of the other former tribe's members. Named for the Pagong tribe in the first season, who was the first victim of this.
Ulonging - Before the merge, one tribe regularly wins immunity challenges, forcing the other to continually lose members. Named for the Ulong tribe in Palau, who lost every single challenge and was down to one person by the time the "merge" came.
Idoled - When a player saves themselves from elimination with an Immunity Idol, the player who gets voted out instead has been "idoled".
Loser Lodge - The complex where jury members stay after getting voted out. Officially called the Ponderosa.
The Tyler Perry Idol - An extra-secret, even more powerful version of the Hidden Immunity Idol. Named so since Tyler Perry himself came up with the idea.
Pack Mom - Stiles, especially by the Sterek shippers who see Stiles as the mom to Derek's Alpha/Pack Dad.
People have also taken to calling Derek "Sourwolf" after Stiles called him by the name in one episode.
Stile's dad, having no established first name, has been affectionately dubbed Papa Stilinski.
Top Chef: TV's Jesse Spencer - Jeff of season 5, for looking remarkably like Dr. Chase from House or simply.... Chase - numerous people refer to him by this name and were genuinely surprised upon being informed that that was not in fact his name.
Captain Spike - Captain John Hart of Torchwood, played by James Marsters.
Myfanwy - Is what the cast and production team named the CGI pterodactyl in Torchwood, or perhaps what they named the stand in prop used before the CG is added. This has spread to the fandom and more-or-less supplanted the previous fan-nickname of "Bob" once it was revealed. It has also led fans to the conclusion that the pterodactyl is female, as Myfanwy is a female name.
Coffee bagging - Petitioning for Ianto to return to the show, despite the producers stating that he's definitely dead. Refers to fans who sent bags of coffee to the BBC in protest after the character's departure.
The Nine Hysterical Women - The people that were upset at the death of Ianto Jones, coming from when RTD claimed that that was all the people who had written in or were upset when it happened. Many use it to prove that RTD killed him off because he had a larger fan base than Gwen. FYI, there are more than nine.
Three Kingdoms: Actor Yang Tong became "king of minor roles" (龙套帝) to the Chinese fandom after fans noticed that he had made over twenty separate appearancesspanning almost the entire series, with two of those roles being in the same episode (both for Wu), his total appearances spanning least five different factions (including all three kingdoms), and one of them being a named and plot-relevant character. To make it funnier, almost all of the unnamed roles were also speaking roles.
The Tudors: Thomas Boleyn is generally referred to as Papa Boleyn. Henry VII (not a character, but still discussed) is Papa Tudor. Katherine Howard is often called Kitty, while the soon-to-appear Katherine Parr is called Kate. These last two seem to have historical basis and are also a way of telling the last two Katherines, who were wives five and six, apart - not to mention distinguishing them from wife number one, Katherine of Aragon.
Mandyville — where Mandy went after she was Put on a Bus with no explanation, and where other characters (Ainsley, Danny, Mallory) sometimes visited her. This one is sometimes applied to other shows, probably thanks to Television Without Pity.
The Fab Four: Toby, CJ, Josh and Sam.
The Jackal: CJ, after her famous lip-synching of "The Jackal": "I'm the firmest of the firm/And in case you hadn't known/They call me the Jackal."
Rosslyn: the assassination attempt in Rosslyn, Virginia that occurred in the Wham Episode "In The Shadow Of Two Gunmen" (I&II). Many West Wing discussions divide the timeline into "Pre-Rosslyn" and "Post-Rosslyn".
The Organization - the sinister group that the Smoking Man and Strughold work for.
Cigarette Smoking Man, a.k.a. Morley Man (after his preferred brand), a.k.a. Cancer Man. "Cancer Man" eventually started being used in the show itself. "Marlborough Man" has also been used, after the source of the expied brand used in the show and the spokes-character introduced to sell it after it was switched from being a "woman"'s brand.
The Schwarzenalien, the Mighty Morphin Bounty Hunter - Shapeshifting alien played by Brian Thompson.
The Fowl One - Diana Fowley (also reffered to by more colorful names).
Plam - the knife with the retractable blade that the show implied was THE ONLY weapon that could kill the aliens. Named from a moment when Mulder's mother was trying to tell him she'd hidden one in her lamp - but she'd had a stroke, so "lamp" came out "plam."
