A character of superlative intelligence and a superlative lack of hygiene. This type of character is seen at pretty much every variation of the [[CharacterAlignment alignment spectrum]], and is usually associated with the image of the reclusive hacker. Usually, their slovenliness is combined with NoSocialSkills -- whether it's a tendency for bluntness or extreme timidness, as well as a tendency for unsavory habits and eccentricity. The character's clothes will typically be [[RummageSaleReject unstylish]] and [[RainbowPimpGear mismatched]] as well as rumpled and dirty. Good guy genius slobs are usually portrayed as just being too dedicated to their vocation to have much time for hygiene, while the filth on bad guy genius slobs is used as an outward reflection of inner rottenness.

Keep in mind that this is not a genius who is constantly filthy ''because'' of his job. A genius engineer who's constantly dirty from working on machines is not a genius slob, he's just dirty because in his line of work it's inevitable. This trope specifically refers to geniuses who are filthy in their personal lives. It's not a consequence, it's a character trait.

Subtrope of BrilliantButLazy. May go hand in hand with the monomaniacal focus of TheMadnessPlace. In extreme cases, overlaps with ThePigPen.



[[folder:Anime and Manga]]
* ''Manga/AttackOnTitan'': Hange Zoë is an excitable scientist who gets so caught up in her work that Captain Levi needs to knock her unconscious and forcibly bathe her. Being the NeatFreak he is, he has to remind her of hygiene in general.
* ''Manga/Brave10'': Yukimura is TheStrategist but Rokuro is constantly his case for dressing slovenly, not [[MessyHair brushing his hair]], and generally not conducting himself as a samurai ought to.
* ''Anime/BubblegumCrisis'': The Hacker from the old ''AD Police'' [=OVAs=], who was overweight, always barefoot, and could barely move within his apartment from all the crap lying around.
* ''Manga/DGrayMan'': Supervisor Komui. Science genius and one of the most important members of the Black Order. So disorganized you can't see the floor of his office.
* ''Manga/DeathNote'': L, while not as filthy as other genius slobs, is VERY eccentric, a challenge to have a conversation with, and always has a disheveled appearance and [[DoesNotLikeShoes bare feet]]. His eating habits leave a lot to be desired, too.
* ''Anime/EdenOfTheEast'': The genius programmer Yutaka Itazu just put the finishing touches on a computer-program that can predict the future. He also lives in an apartment that's so messy he's practically had to dig tunnels though the rubbish, never leaves it, and never wears anything but underwear. His excuse is that his only pair of pants blew away when he was drying them, hence his nickname of 'Pantsu'...
* ''Anime/EurekaSeven'': Dr. Greg "Bear" Eagan is a reclusive, slovenly, colossally fat man who only seems to eat candy -- and an absolutely brilliant scientist.
* ''Anime/GaoGaiGar'': Kosuke Entouji could pretty much be the ultimate example of this trope. A very good guy, essential to the 3G's operations as their information analyst, and thoroughly disgusting hygiene. His workspace is a total mess of empty snack bags and magazines(not to mention many fans have suspicions about that [[ADateWithRosiePalms box of tissues...]]), and he'll go for days at a time without taking a bath. Every time he scratches his head, a cloud of dandruff erupts from it.
%%* ''Manga/HunterXHunter'': Dwun.
* ''Anime/JewelpetKiraDeco'': Sapphie far prefers using her free time to learn new things than to do any chores around the house. As a result, it's always a mess.
* ''Manga/MahouSenseiNegima'': Hakase. She sleeps in her lab sometimes and leaves her underwear lying around, [[http://www.mangafox.com/manga/mahou_sensei_negima/v09/c075/2.html which gets comments from the guy scientists who share the lab.]]
* ''{{Manga/Saiyuki}} Gaiden'': Marshall Tenpou. A brilliant tactician and historical scholar, he deduces the corruption in Heaven's army well before any of the other protagonists. His subordinate General Kenren has to remind him to [[ForgetsToEat eat]], sleep, and bathe periodically, and also cleans his office for him: Tenpou never puts anything away after reading it, causing his office to become an avalanche of books and scrolls within a month.
* ''Anime/StrikeWitches'': Erica Hartmann, one of the squad's top ace's in the air, lazy slob on the ground.

* From ''Film/JurassicPark'', both food addict networking director Dennis Nedry and chain-smoking control room chief John Ray Arnold.
* ''Film/TheMartian''. Our first sight of Rick Purnell, who comes up with the SpaceshipSlingshotStunt that saves the day, is him asleep on the couch in his office at JPL with papers and other junk piled everywhere.
* In the first ''Film/SpiderMan1'' movie, we get this exchange, upon entering Peter's room.
-->'''Norman Osborn:''' Bit of a slob, isn't he?\\
'''Aunt May:''' All brilliant men are.

* Helen Burns in ''Literature/JaneEyre'' is something of this. She's a brilliant student and very mature for her years, but is constantly lectured about her dirty nails and untidy appearance. Miss Scatcherd writes the word SLATTERN (slob) on a piece of cardboard and ties it to Helen's head. This is all very likely to have happened to Charlotte Bronte's sister Maria, on whom Helen is based.
* ''Literature/TheMillenniumTrilogy'': Plague, Lisbeth's hacker friend in ''The Girl with the Dragon Tattoo'', is balding, overweight, smelly and supposedly has a porn collection to baffle minds. He's also a genius with computers (both their construction and programming), and is a master investigator, able to get information for Lisbeth that she has trouble finding (or getting access to).
* ''{{Literature/Paprika}}'': Tokita. He's fat, clumsy, and his work area is a mess. [[spoiler:Doesn't stop him from getting the girl in the end, though.]]
* Evil Smelling Bugger from ''Discworld/{{Pyramids}}'' is the greatest mathematician on [[Literature/{{Discworld}} the 'Disc]] as well as being a camel.
* ''Literature/SherlockHolmes'': Holmes, of all people. Yes, his living room and general appearance to the public is neat and fastidious, but walk past the curtain into his study and you'd be flabbergasted at the enormous clutter of evidence and experiments. The Creator/GuyRitchie-directed [[Film/SherlockHolmes2009 film]] starring Creator/RobertDowneyJr illustrates it excellently, and in the [[Series/{{Sherlock}} modern version]] Holmes drives Watson crazy by, for example, keeping severed heads in the refrigerator and eyeballs in the microwave.
** Holmes is a slob with respect to his home and belongings, but not in his appearance -- in fact he is said to have a "catlike love of personal cleanliness". FridgeBrilliance: he'd not want to contaminate a crime scene.
* From Creator/MaryGentle's ''Literature/WhiteCrow'' stories, Baltazar Casaubon: A brilliant architect and/or hacker (depending on the exact story)... who's almost invariably either freshly bathed, or absolutely covered in dirt, grease, and [[BigEater food stains]].
* Snout in Helon Simonson's ''Literature/TheSummerBeforeTheWar''. He drinks noisily and often wants to skip tutoring sessions, but he understands Latin well and appreciates literature, particularly ''Literature/TheAeneid''.
* In the ''Literature/DresdenFiles'' Murphy's partner Carmichael is noted to be a slob as well as sharp, ruthless, and an all-around excellent cop.

[[folder:Live Action TV]]
* Franchise/SherlockHolmes in ''Series/TheAdventuresOfSherlockHolmesAndDoctorWatson'' is, true to the books, reasonably well groomed but not inclined to clean up after himself. He doesn't even want Mrs. Hudson to dust his things, and he seems to dislike cleaning in principle because it destroys evidence.
* Likewise, Sherlock Holmes in ''Series/{{Elementary}}''. Papers, files, the detritus of experiments and dirty dishes crowd every surface in the brownstone, much to Watson's exasperation, although the introduction of Ms. Hudson might change this.
* Cameron Howe from ''Series/HaltAndCatchFire'' is a programming prodigy; however, her unprofessionalism and unkempt appearance often clash with the corporate environment of Cardiff Electric.
* Onslow from ''Series/KeepingUpAppearances'' is a FatSlob with a broken-down car on his lawn, but is regularly shown reading grad-school level philosophical texts.
* Oscar the Grouch from ''Series/SesameStreet''. He loves trash and garbage, but can be rather ingenious with it. He's built a RobotBuddy out of junk, and his trashcan has a dimension gate to Grouchland USA, his hometown (which he presumably built) and he can train worms to sing.

* The MadScientist's desk in ''Pinball/StrangeScience'' is cluttered with various bits of trash, including a half-empty can of cola, a partially-eaten cheeseburger and a tube of ketchup.

[[folder:Video Games]]
* ''VideoGame/{{AkaSeka}}'': Mori Ōgai may be a cute, smooth-talking, successful writer, but his place is an absolute mess, so much so that it earned this little gem from [[{{Cloudcuckoolander}} Natsume Sōseki]] when he sees his apartment for the first time.
--> '''Sōseki:''' Has a storm gone through here?
* ''VideoGame/EarthBound'': Apple Kid.
-->'''Apple Kid''': I haven't taken a bath in a while, so I may be kind of stinky.
* ''VideoGame/MetalGearSolid'': Otacon in the first game was prone to this. He cleans up in the sequels though.
* ''VideoGame/PokemonRubyAndSapphire'': Lanette is the Pokemon Storage System designer, and her house on Route 114 ''is a mess''. When you visit her there, she's embarrassed, and gives you either a Seedot or Lotad doll (depending on the version) in exchange for keeping quiet about it.
* ''VideoGame/SaintsRowTheThird'': If teamed up with a particular homie, ex-FBI hacker Kinzie Kensington reveals she doesn't even know ''how'' to wash her hair.

[[folder:Web Original]]
* Kenneth Kennethson, LetsPlay/NerdCubed's sim from VideoGame/{{The Sims}} 3 series had the "Genius" trait, and was seen digging through thrash.

[[folder:Western Animation]]
* ''WesternAnimation/BojackHorseman'': The eponymous character, believe it or not. For a narcissistic, whoremonger, wreck of a celebrity whose parties often leave his house a mess and doesn't even bother that much with any cleaning, [=BoJack=] has a surprising sharp mind when dealing with intellectual matters (e.g. smart conflict resolution of the Israeli-Palestinian issue in [[Recap/BojackHorsemanS2E07HankAfterDark "Hank After Dark"]]; slightly inaccurate but sound views about the French Revolution and [[Creator/JeanPaulSartre Sartre]] in [[Recap/BojackHorsemanS2E8LetsFindOut "Let's Find Out"]] and [[Recap/BojackHorsemanS3E04FishOutOfWater "Fish Out Of Water"]]). His personal life remains a mess, though.
* ''WesternAnimation/GravityFalls'': Dipper Pines is noted to bathe rarely and wash his clothes next to never. True to the trope description, it seems to be because time spent on hygiene is time spend not solving mysteries and hunting monsters.
-->'''Dipper''': Washing clothes is a waste of time - I'm a busy guy!
* ''WesternAnimation/TennesseeTuxedoAndHisTales'': Mr. Whoopie is a genius who seems to be able to give advice on any subject, but he can never seem to keep a clean closet. [[RunningGag Every time he goes to get the 3-Dimensional blackboard from it]] to use as a visual aid, an avalanche of junk comes crashing down on him.

[[folder:Real Life]]
* The Greek philosopher [[https://en.wikipedia.org/wiki/Diogenes_of_Sinope Diogenes]] purposely lived like a slob in a way resembling poverty, because he taught by example. Being a Cynic, he rejected society and everything it entailed, such as hygiene and social skills. The behavioral disorder Diogenes syndrome, named after him, is characterized by self-neglect and hoarding.
* According to UsefulNotes/NikolaTesla, UsefulNotes/ThomasEdison 'lived in utter disregard of the most elementary rules of hygiene'.
* Michelangelo was a real life historical example. He apparently only took a bath twice a year or so, something considered disgusting even in those days.
* The BrilliantButLazy Music/JohnLennon, though you could also chalk up his style to lax hippie-era standards.
* UsefulNotes/AlbertEinstein was a chain-smoker (even going as far as picking up cigarette butts off the street when his doctor tried to curb his tobacco intake), a scruffy dresser (avoiding socks and combing his hair), and a great proponent of messy workspaces - "If a cluttered desk is a sign of a cluttered mind, of what, then, is an empty desk a sign?"
* Music/LudwigVanBeethoven
* UsefulNotes/IsaacNewton rarely changed his clothes or combed his hair. The combination of alchemical experiments and obsessive note taking left his rooms such a mess that it was both a potential fire hazard, (see the story of his dog Diamond,) and a pain in the ass for the collaborative efforts of Edmond Halley.
* [[https://en.wikipedia.org/wiki/Howard_Hughes Howard Hughes]] hated other people's germs, but he did not mind his own. He apparently liked to sneak around his factory spying on his employees but he was usually given away by the horrendous smell of old tennis shoes he constantly wore. And this was before he locked himself away with jars full of his own urine.
* This is characteristic of certain types of autism. There is also [[http://arianebenefit.com/blog/2011/10/19/truth-about-chronic-disorganization-understanding-what-causes-chronic-disorganization-and-how-to-heal-the-trauma-of-lifelong-disorganization-overwhelm-and-frustration/ chronic disorganization]]. This is not officially classified as a mental disease, but a behavioral trait often resulting from life stresses. Professional organizers emphasize developing systems based on individual personalities rather than trying to arrange things as "normal" people do. Not all chronic disorganizers are autistic, but may have [[http://arianebenefit.com/blog/2011/10/05/who-are-outliers-and-what-is-neurodiversity/ non-autistic neurodiverse personality traits]].
