-> ''"There's already two Xs in Xbox, you dozy gits, this name's starting to look like a defaced game of TabletopGame/TicTacToe!"''
-->-- '''[[WebAnimation/ZeroPunctuation Ben "Yahtzee" Croshaw]]''' on the Platform/XboxOne X

A variant of XtremeKoolLetterz, seen used in both work titles and in names.

The letter X [[LetXBeTheUnknown is already fascinating]] and [[XMakesAnythingCool cool]], so double the X, double the awesomeness! Right? Much like XtremeKoolLetterz, it's often meant to evoke badassery, or lend the show an air of youthful [[TotallyRadical hipness and coolness]]. Alternatively it's often associated with PornNames, especially when you add a third Xs. Tripling the Xs is also associated with moonshine.

How exxactly you're supposed to pronounce this is usually unclear.

Not to be confused with Music/TheXX, though they are an exxample of this trope.

!!Exxamples:

[[foldercontrol]]

[[folder:Advertising]]
* Advertising/TheMostInterestingManInTheWorld doesn't always drink beer, but when he does, he prefers Dos Equis ([[labelnote:XX]]from Spanish, literally "double X"; the beer was first brewed around 1897 and initially called "Siglo XX" (20th Century), but the prominent double X logo earned it the nickname "Dos Equis"; this nickname was eventually made its official name.[[/labelnote]]). Stay thirsty, my friends.
[[/folder]]

[[folder:Anime and Manga]]
* ''Anime/AfterWarGundamX'' has, of course, the MidSeasonUpgrade MS, the "Gundam Double X". However, this is [[JustifiedTrope justified]] in that it was designed to possess double the firepower of the Gundam X, as well as two [[WaveMotionGun Sattelite Cannons]], essentially making it twice the Gundam the X was. It's also played with in that despite its pronunciation, "XX" appears ''nowhere'' in its name or designation.
* However, the designations of the Gundams in ''Anime/MobileSuitGundamWing'' play this straight, with all of their alphanumerics beginning with "XXXG".
* ''Anime/DarlingInTheFranxx'', after the titular mecha, in turn named after their creator Dr. Franxx. The XX turns out later to have grater significance: [[spoiler:chromosomes. Klaxosaurs and Franxx alike are built of bio-metal with entirely XX DNA. Dr. Werner Frank changed his name after meeting the Klaxosaur Princess and [[AdmiringTheAbomination going loopy for her]].]]
* ''Manga/LoveGeneXX'': is a sci-fi {{yuri}} romance set in a futuristic LadyLand- in this case the "xx" refers to the fact that the love interests (and all other characters) have XX chromosomes.

[[folder:Card Games]]
* ''TabletopGame/{{Fluxx}}''
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/TheMaxx''
* Creator/MarvelComics' Roxxon Energy Corporation, a BrandX of Exxon (see RealLife section).
[[/folder]]

[[folder:Film]]
* The German movie ''Film/DerWixxer''.
* Foxxy Cleopatra from ''Film/AustinPowersInGoldmember''.
* Averted in ''Film/TheGreatDictator'' where the [[ANaziByAnyOtherName Nazis By Another Name]] use the XX (the "[[VisualPun Double-Cross]]") logo [[NoSwastikas in place of the swastika]].
* ''Film/{{Traxx}}''
* Agent Triple X is the codename of Bond's DistaffCounterpart in ''Film/TheSpyWhoLovedMe''. It also serves as the obligatory [[DoubleEntendre suggestive]] BondGirl name, given that her actual name is [[WhenHarryMetSvetlana Anya Amasova]].
[[/folder]]

[[folder:Literature]]
* The Taxxons from ''Literature/{{Animorphs}}''.
* When Max Barry wrote the book ''Syrup'', he authored it under a byline of "Maxx Barry". When he wrote Literature/JenniferGovernment, he considered making it 3 Xs before settling back on 1.
* The Franchise/StarWarsExpandedUniverse gives us a character with the alias [[LeetLingo Teh Roxxor]].
* A story in Carl Sandburg's ''Literature/RootabagaTales'' features a young woman with a fondness for suitors with Xs in their names: she sequentially dates men with the last names Bixby, Axenbax...and Sixbixdix.
[[/folder]]

[[folder:Live-Action TV ]]
* The spaceship Series/{{Lexx}}, from a series of the same name.
* German game show ''[=GoXX=]''.
* The German show ''Reläxx''.
* The main character (and host) of ''Series/DoubleTheFist'', Steve Foxx.
* In one episode of ''Series/HowIMetYourMother'', a fake magazine (featuring women bodybuilders) called ''Muscle Sexxy'' is mentioned.
[[/folder]]

[[folder:Music]]
* Music/{{Scooter}}'s lead vocalist H.P. Baxxter, whose real name is actually Hans Peter Geerdes. H.P. first started using the surname Baxxter back in the 80s when he was part of the synthpop group Celebrate The Nun, and it was no-doubt chosen because of gothic coolness associated with the double x.
* Music/{{Underworld|Band}}'s Born Slippy (N.U.X.X.)
* Music/TheyMightBeGiants' "S~E~X~X~Y", which is always pronounced as the 5 letters. Not explained, except "because it's extra, baby".
* Music/TheXX named themselves after this, although they were originally X until they realised there were other bands with that name (their album cover was kept the same).
* 2020's Korean Pop group Music/{{NMIXX}}, and yes they admit the double-x is meant to evoke coolness.
* There are numerous bootleg compilations called Ultra Rare Traxx or Trax. Calling them 'Traxx' was a way of disguising the fact that they weren't always songs.
* Music/{{Outkast}}'s ''Speakerboxxx/The Love Below''.
* Nikki Sixx of Music/MotleyCrue, Sixx:A.M., etc.
* Basement Jaxx
* New Wave rock band Music/TheFixx are an enforced example. The band were performing as The Fix when they started negotiating their first major label record deal, but MCA refused to sign them with that name because of the drug connotations. Adding a second x was an acceptable compromise for both sides, and the deal was struck.

[[folder:Professional Wrestling]]
* The infamous Axxel, although in this case it is almost certainly WritingAroundTrademarks, as his infamy comes from his uncle, El Hijo Del Santo's, attempts to end his career, often with threats of legal action against promotions that book him.
* When Wrestling/{{WCW}} signed the USWA wrestler Max Pain, he of course became Wrestling/MaxxPayne, because the regular spelling apparently wasn't hardcore enough for [[NinetiesAntihero the 1990s]]. This is also where [[Wrestling/SeanWaltman the 1-2-3 Kid became Syxx]].
* Wrestling/{{WCW}} also had Maxx Muscle, a [[BattleButler bodyguard]] for Wrestling/DiamondDallasPage, who later joined the Wrestling/DungeonOfDoom.
* Dropkixx Promotions, an enterprise based in London of the UK. Among the title belts they hosted defenses of was the Wrestling/{{N|ationalWrestlingAlliance}}WA United Kingdom Junior Heavyweight Title, which was once won by Beau Jaxx...
* Sexxxy Eddy of Canada's International Wrestling Syndicate, then nCw, then Wrestling/{{CZW}}...
* Miss Rachel was known as Pandora Boxxx when she wrestled in France and The UK, prior to [[DefeatMeansFriendship being defeated by and marrying LT Falk]], then relocating to the southern USA.
* Jorge Estrada, who wrestled for NWA Wildside and Wrestling/{{ECW}}. A [[LatinLover Latin Heartthrob]] so Hexxy they had to spell it with two xs.
* Magnitude Kishiwada and Gamma teamed as "[=FluXxx=]" in Osaka Pro and Wrestling/DragonGate.
* Jaimy [=CoxXx=], most commonly wrestling in the Detroit based XICW, although his suggestive name unsurprisingly comes from Wrestling/JuggaloChampionshipWrestling.
* Nikki Roxx of the Killer Babes, Pretty Bitchin and Wrestling/{{Daffney|Unger}}'s All Star Squad...or Roxxi Laveaux to you [[Wrestling/ImpactWrestling TNA]] fans. No relation to NWA World Women's Champ Tiffany Roxx...
* Julie The Red Fuxxx, [[EagleLand a miscreant from south of the boarder]] who [[GermansLoveDavidHasselhoff became the female face]] of northern Championship wrestling, prior to the Femme Fatales SpinOff built around [=LuFisto=](nCw is very fond of nonstandard letter use, if you couldn't tell).
* Bryan Alvarez's slightly less famous but much more successful TagTeam partner in the Canadian ICW, Nicki Sixx. He had a temporary DistaffCounterpart when The Black Rose Nikki Adams briefly went by Nikki Syxx in Wrestling/{{WSU}}.
* AJ Sparxx...though this might be just to distinguish him from the female AJ Sparks(who people naively believed pre Wrestling/GailKim TNA would do something with)...
* Bexx, better known in the UK as Zak Zodiac of the [[WrestlingFamily Knight family]].
* Strong man Jaxx from the German Wrestling Federation's school.
* Ashley Sixx, or Ash for short. Given "Ashley" [[GenderBlenderName is a common woman's name in Canada]], the extra x seems to be something to make these guys seem more manly, as if Ashley's sideburns weren't enough. There's also a Kelly Sixx, who mainly wrestled in the UK and eventually settled on the much less ambiguous ring name "Josh".
* Ann Brookstone, whose disgusting habits earned her the nickname "Ann Thraxx".
* NWA Top Of Texas and NWA Midwest had "Biohaxxard" Jeremiah St. James, a heavyweight champion of the former.
* Lexxus, later known as Alexxis Nevaeh and "[[RedBaron The Double X Diva]]".
* Before he was Wrestling/SethRollins, before he was Tyler Black, before he was Taj The Destroyer, he debuted for Scott Country Wrestling as Gixx!
* Stix and Stone, the TagTeam of Martin Stone...and Stixx in the UK.
* Wrestling/JonMoxley was sometimes billed as "Moxley Moxx" in IWA Puerto Rico, [[IWasBeatenByAGirl most famously]] when he lost the hardcore belt to then rookie sensation La Amazona.
* Wrestling/{{CMLL}} and Wrestling/{{AAA}} have the Gargoyle luchador Groon XXX on their {{B show}}s. There is also a Mini Groon XXX on the Mexican independent circuit.
* Maxx Stardom, who only spells his Spanish name, Maximo Estrella, with one x. Then again, he ''originally'' just when by Max Stardom in English too until his TagTeam with Mykal Manix started breaking down...
* Austrian wrestler Max Moran is frequently billed as "Mexx" and "Mexxberg". This may be in reference to the Nordic fashion company, and, of course, Wrestling/{{Goldberg}}.
* Wrestling/ChristinaVonEerie became "Toxxin" when officially signed to TNA.
* Subverted with the XX title belt of Texas based Inspire Pro Wrestling. It means "ladies only".
* Madi Maxx, who purposefully spells it that way to annoy people. She "loves haters".
* Andrew Palace and Chest Flexor teamed as "Flexxx Palace" in the International Wrestling Cartel.
* [=Hi69=] and Taiji Ishimori originally teamed with Wrestling/KotaIbushi for a joke in Wrestling/DramaticDreamTeam. However, twelve years later, they would reunite without him much more seriously as XX, decisively winning Wrestling/ProWrestlingNOAH's GHC Junior Heavyweight TagTeam Titles and ''almost'' winning AAA's Lucha Libre World Cup.
* Axx Clover, an aptly named GarbageWrestler most commonly seen around Florida, especially AWE's Hardcore Division.[[/folder]]
