By definition: someone who's left-handed instead of right-handed or ambidextrous.

Traditionally, baseball fields were oriented so that the batter, catcher, and umpire faced east to ensure that the setting sun wasn't in their eyes. As a result, when a pitcher is on the mound facing home plate, his left hand pointed south, so lefty pitchers came to be known as southpaws. The term has since entered general usage to indicate left-handed people. There is a perception that southpaws have an [[http://www.newsweek.com/id/146842 advantage,]] because they are different from right-handed opponents. And it has proven to be TruthInTelevision in quite a few sports, besides baseball. For example, left-handed sword fighters' attacks come from an unusual angle compared with those by right handed opponents, making them more difficult to parry. And left handed--er, footed--soccer players have a likewise advantage over right handed goalkeepers, making them ideal for penalty kicks. As a result, in many sports the proportion of left-handed players is significantly higher than in the general population.

An inversion, '''Situational Southpaw''', exists when the character is not normally left-handed, but is forced to become left-handed, either through [[TrainingFromHell forceful education]], [[AnArmAndALeg injury]] or some apparatus that disables the character's right hand or arm ({{Arm Cannon}}s are a popular choice).

In real life, very few people are completely hand-dominant, either right- or left; it is common to prefer the use of the non-dominant hand for a few tasks, such as writing or sport. In fiction left-handedness is used as a defining characteristic, and is often treated as a slight positive. For left-handedness as a sign of evil see ASinisterClue.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Manga/DiamondNoAce'', as a baseball manga, has many lefties among its ranks. Protagonist Sawamura Eijun and major antagonist Narumiya Mei are the two most important examples. However, oddly, there's no real advantage to being a Southpaw in-series aside from the standard "slight advantage against left-handed batters"; of the strongest pitchers, fully half are right-handed, including [[spoiler:the Ace of the back-to-back National Champion Komadai Fujimaki High, Hongou Masamune]].
* ''Manga/RurouniKenshin'''s Saitou Hajime. Since all Japanese sword techniques are taught strictly right-handed, the switch could be very useful in the context of kenjutsu.
* ''Manga/BlackCat'''s Train Heartnet was born left-handed and became ambidextrous through training, though his left hand is still slightly faster and more accurate when he uses his gun. Notably, he spends the entire Battle on Clarken Island using his left hand alone, partly to show how [[LetsGetDangerous seriously]] he is taking the job and his opponents.
* Mio Akiyama in ''Manga/KOn'' plays her bass guitar left-handed, and is also shown to use her left hand for writing. She also tends to be fascinated by by ''anything'' meant for left-handed use.
* The ability to box left-handed is a rare and (sometimes) major advantage in ''Manga/HajimeNoIppo''. The ability to switch between southpaw and a conventional stance at will is even better.
* ''Anime/{{FLCL}}'': Haruko and, supposedly, Naota's brother are southpaws (a guitar [[ImprobableWeaponUser "player"]] and baseball player respectively), as pointed out in the DVD commentary. Apparently it has something to do with their coolness, according to the director's opinion.
* Inverted with Riffael Raffit of Manga/CountCain -- his right hand was injured badly enough after [[spoiler:his suicide attempt in the hospital]] that he had to learn to use his left. After it heals, he remains left-handed. [[spoiler: When his evil SplitPersonality regains control over his body, it's right-handed -- and when good-Riff starts his SplitPersonalityTakeover, he shoots himself in the right arm to hamstring evil-Riff.]]
* Videl, from ''Manga/DragonBall'', is a lefty: she is seen pitching baseballs and writing with her left hand.
* While ''Franchise/LyricalNanoha'' has a few left-handed characters, including the titular character. There are two examples that fit this trope.
** Alicia being left-handed is the first evidence for Presea to see Alicia's right-handed clone Fate as a failure.
** [[{{Cyborg}} Ginga]] is not only left-handed, her left hand can even turn into a drill, something that her right-handed younger sister Subaru lacks, giving Ginga an advantage in armory and close-range combat.
* ''Manga/YugamiKunNiWaTomodachiGaInai'' has [[LonersAreFreaks loner]] [[TheProtagonist protagonist]] Yugami, the left-handed [[TheAce ace]] of the school's baseball club. He also writes left-handed. Considering the rest of the cast appears to be right-handed, this serves to further accentuate Yugami's eccentricity and isolation.
* Inverted with Barret in ''Anime/FinalFantasyVIIAdventChildren'': he suffered a gunshot wound that made his right arm unusable. It's likely he was right-handed before this wound. However, he might have simply gotten used to using his left by this point, as his gun-arm is now capable of assuming the form of a usable hand.
* Sen Takatsuki from ''Manga/TokyoGhoul'' is left-handed, writing with her left hand during her autograph session. This turns out to be [[ASinisterClue significant]] later on.
* Stocking in Anime/PantyAndStockingWithGarterbelt is shown to be left-handed, in a way making her the LeftHandedMirror to her (opposite in personality) older sister, Panty.
* Graham Aker of ''Anime/MobileSuitGundam00'' is also a left-hander, as evident with his AceCustom units.[[labelnote:Clarification]]Not counting the mass-production Union Flag he used when he first encountered the Exia, all of his suits have their primary weapons held by their left hands. As to the dual-wielding [[SuperPrototype Masurao and Susanowo]], the longer blades are always held by the left.[[/labelnote]]
[[/folder]]

[[folder:Comic Books]]
* ComicBook/{{Hellboy}} is an inversion. A huge stone hand isn't really useful for doing anything other than punching things, which makes him left-handed out of necessity. Conveniently, Ron Perlman who portrays him in the films is also left-handed.
* {{Subverted}} with [[FallenHero Hector Sinestro]] of ''ComicBook/MonsterAllergy'': he has ''two'' left hands, but he's not left-handed, something that greatly irritates him.
[[/folder]]

[[folder:Films -- Animation]]
* ''WesternAnimation/HowToTrainYourDragon'''s Hiccup is noticeably left-handed, possibly to emphasize his role as a misfit. This is carried over from the [[Literature/HowToTrainYourDragon original books]], where his handedness becomes a plot point.
* Anika Noni Rose requested that Tiana from ''Disney/ThePrincessAndTheFrog'' be left handed like her. In many scenes (pouring coffee, stirring something, writing her name in a dream sequence)she uses her left hand but minces with her right hand (well, flipper as she's a frog at this point). Maybe she's ambidextrous.
* Disney/{{Mulan}} writes left-handed, but uses a sword right-handed.
* In ''Disney/{{Frozen}}'', Elsa shows a preference for ice shooting left-handed.
[[/folder]]

[[folder:Films -- Live-Action]]
* Actor BruceWillis is left handed, thus so is John [=McClane=], the main character in the ''Film/DieHard'' franchise. However, in the movie ''Film/SinCity'', Willis wielded his gun right handed to accurately depict the character of John Hartigan, who was right handed in the original comic books.
* Zigzagged with ''Film/{{Rocky}}''; he was a left-handed boxer, which led (in his backstory) to opponents refusing to face him out of fear that it would mess with their mechanics. He defeats the world champion by learning to fight righty for most of the fight, and then switch to his natural stance and go for the KO.
* Inverted in ''Film/ThePrincessBride'': both the Man in Black and Inigo Montoya fight left-handed in their duel as a way of handicapping themselves to give their opponent more of a fight. Eventually they both [[IAmNotLeftHanded drop the act]] and fight better with their right hand.
* Inverted in the original ''Franchise/EvilDead'' films, in which Ash actually ''loses'' his right hand. Of course, Creator/SamRaimi probably decided that Ash should lose his right and not his left hand because Creator/BruceCampbell in RealLife is left-handed.
* Due to their actor being left-handed, both Alan Bradley and his Program Film/{{Tron}} are left-handed. This seems to make Tron unique among Programs, as no other Programs appear to share that trait. [[note]] The ''WesternAnimation/TronUprising'' animators sometimes forgot this, but Beck being right-handed was one of the ''many'' giveaways that he wasn't the genuine article [[/note]]
[[/folder]]

[[folder:Literature]]
* ''Literature/ASongOfIceAndFire'':
** Arya Stark. When her dominant hand is revealed to her fencing master, he reacts favorably because fighting left-handed will reverse her stance and movements, which will help confuse her opponents. Of course, her left-handedness might also be ASinisterClue about her future.
** Qhorin Halfhand and Jaime Lannister are both inversions; both lost their right hands (Qhorin lost several fingers, Jaime the entire hand) and were forced to learn to fight left-handed. Jaime's struggles to regain his swordsmanship post-amputation take on the flavor of TrainingFromHell.
* Downplayed in Creator/HarryTurtledove's ''Literature/TalesOfTheFox'' series: the main character is left-handed, and he remarks that it makes it easier to get around enemy shields for a couple of reasons.
* Inverted in the ''{{Emberverse}}'' novels: Rudi Mackenzie's right arm is wounded and has to learn to use his left arm as his sword arm. When practicing with youths in the Free Republic of Richland they complain that he has an unfair advantage as a southpaw. His mentor responds "Yah hey, if someone attacks you using different moves, or if they're a leftie you're just going to say you're taking your bat and ball and going home 'cause it ain't fair? Christ, Weiss, I've known you were a dumb little punk for years, but do you have to show it off in front of strangers?"
* Parodied in ''Literature/TheSilmarillion'': [[HandicappedBadass Maedhros]] learns to wield his sword with his left hand after a LifeOrLimbDecision. He becomes even more deadly afterwards (though this is probably for psychological reasons more than anything physical.)
* Dhugal in the ''Literature/{{Deryni}}'' novels is noted as left-handed, including fighting left-handed. The narration in the archery yard scene in ''The King's Justice'' recounts the late King Brion's preference for his pages and squires to train right-handed (which Dhugal missed by spending much of his training years at home in Transha). Brion was grudgingly persuaded by Alaric Morgan that fighters should know how to switch off in case of injury (so as not to be left defenseless), but even a couple of years after Brion's death, Dhugal stands out as the only left-handed fighter. Dhugal will have reason to appreciate Morgan's logic in ''The Quest for Saint Camber'' when he breaks his left arm [[spoiler: when he's swept away in a rainy landslide]].
* Alanna from the Literature/TortallUniverse deliberately practices at using her sword left-handed after her right arm is injured during training to become a knight. She keeps up the ambidextrous sword usage even after she's healed, which becomes a ChekhovsSkill in a duel against the BigBad.
* Orm, the main character from ''Literature/TheLongShips'', is left-handed as a result of rowing a starboard oar on a slave galley for five years. It is commented upon when he duels, that this makes shieldwork more difficult both for him and the right-handed man he's fighting.
* ''Literature/MarginPlay'': The protagonist, Amber Eckert, is a lefty, although that fact is never specifically mentioned. There are plenty of clues though, starting in the very first chapter when she carries a rolled-up newspaper in her left hand as she approaches an AngryGuardDog. It becomes rather important late in the book.
* Inverted in ''Literature/TheDarkTower'': Due to an unfortunate encounter with "lobstrosities" in ''The Drawing of the Three,'' Roland Deschain loses three fingers of his right hand. From that point forward he's strictly a left-handed shooter. The remaining members of his ''ka-tet'' inherit the use of his right-hand gun.
* ''[[Literature/TheIcelandicSagas The Saga of the Sworn Brothers]]'': Thormod, a lefthander and "not a strong man", is able to kill the great warrior Thorgrim Troll with an axe borne in his left hand, and afterwards makes a poem about the deed which specifically mentions it was done left-handed. This suggests Thormod credits success to his left-handedness, because Thorgrim did not expect an attack from a man carrying a weapon in his left hand.
[[/folder]]

[[folder:Live-Action TV]]
* Inverted in ''Series/DharmaAndGreg'' - Greg's father trained his naturally right-handed son to switch so he'd have an advantage in baseball. When Greg points this can actually be psychologically unhealthy to do to a child, his father seems a little sheepish: "Sorry, son... Won't do it again."
* In one of their sketches, ''Series/HorribleHistories'' outlined some of the the grief that soldiers in the RealLife Georgian-era British Army had to face. One of them was that left-handers were forced to fire their muskets right-handed, since that was the only way to make sure the flash would not blow up in their eyes.
* On the cooking competition show ''Series/CutthroatKitchen'', situational southpaw conditions occasionally pop up. In most cases, right-hand-dominant chefs will be forced to cook left-handed for the duration of a challenge. This results from reduced finger mobility on the right hand or, in more undesirable cases, being forbidden from using the right hand at all. (These conditions also apply to left-hand-dominant chefs who are forced to do most of their tasks right-handed.)
** Additionally, one implement is a "Black and White" table. Unlike the hand-swap handicaps, the Black and White table requires the person using it to perform the same action with both the left hand and right hand at the same time.
* During the last season of ''Series/StarTrekDeepSpaceNine'', Ezri Dax is left-handed, so [[TheNthDoctor in her disorientation as the new host of the Dax symbiote]], she was initially thinking she was right-handed like her predecessor Jadzia.

[[folder:Music]]
* Left-handed guitarists have been a staple of music since the dawn of string instruments. We have Tony Iommi (Music/BlackSabbath), Music/PaulMcCartney, Music/JimiHendrix, Sylvia Tyson, and Music/BillyRayCyrus, [[https://en.wikipedia.org/wiki/List_of_musicians_who_play_left-handed for starters]]. Music/KurtCobain, however, played left-handed but could write with the right.
[[/folder]]

[[folder:Pro Wrestling]]
* Wrestling/{{Carlito| Colon}}'s {{red baron}} in Wrestling/{{WWE}} was the Southpaw from San Juan, given by Wrestling/JimRoss, who tends to shout "Right Hands" when matches degenerate into brawls and noticed there was one guy it did not apply to.
[[/folder]]

[[folder:Video Games]]
* Kain and Palom from ''VideoGame/FinalFantasyIV'' are left handed. [[VideoGame/FinalFantasyIVTheAfterYears The sequel]] reveals Golbez is as well.
* James Anderson in ''VideoGame/{{Outlaws}}'' is left handed. The game is a rare example of a FirstPersonShooter that features a left handed main character.
* Sol Badguy in ''VideoGame/GuiltyGear'' wields his sword left-handed, in ReverseGrip no less. Naturally, he regularly defeats his right-handed [[TheRival rival]] Ky Kiske whenever they go at it. The same applies to Ragna the Bloodedge, the protagonist of Guilty Gear's SpiritualSuccessor ''VideoGame/BlazBlue'', right down to the reverse grip.
* ''Franchise/DevilMayCry'' has Nero in the fourth game, who is a lefty. Though, that most likely has more to do with the fact that his right hand is a demonic claw, so he's probably a situational southpaw. Probably. The new Dante of the AlternativeContinuity is ambidextrous but prefers his left hand. Contrasting classic Dante who was good with both hands, but generally preferred his right hand for Devil Arms and his left for guns.
* Downplayed with Luke fon Fabre in ''VideoGame/TalesOfTheAbyss''. It isn't a major plot point, but it does make for a touching moment at the end of the game, where CoolOldGuy[=/=]ColonelBadass Jade offers his own left hand for Luke to shake, despite being right-handed himself, out of respect for the [[CharacterDevelopment personal growth]] Luke experiences throughout the game. It's also because, in Japan, shaking ones left hand is considered to be a greater sign of trust since that's the one you hold your shield in. Jade is not only recognising Luke's development, but also indicating that he trusts Luke enough to let his guard down in front of him. [[spoiler:Luke is [[LeftHandedMirror "mirrored"]] from Asch due to being his replica--his hair sweeps in the opposite direction from Asch's, too, so it's only natural that they have opposite dominant hands.]] [[spoiler: Asch]] is left handed as well, he just [[BadAss trained himself to use his right hand for everything]] including eating, writing, and sword play because it let him interact with the world better and gives him the advantage of being ambidextrous.
* Dunban in ''VideoGame/{{Xenoblade}}'' is a situational example; he lost the use of his right arm. But still being right-handed or no he kicks ass.
* Link from ''Franchise/TheLegendOfZelda'' is left-handed in every game without motion controls[[note]]excepting cases of AmbidextrousSprite, designers thought it made more sense to have Link's sword appear to be on the right-hand side, but 2D ''Zelda'' titles employ the ThreeQuartersView, where the left-right axes are flipped (Link's left is our right and vice versa); non-motion-controlled 3D Link kept the same handedness preference as a ContinuityNod[[/note]], with the exception of ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]''. [[{{Yandere}} Cia]] from the SpinOff ''VideoGame/HyruleWarriors'' does this as well.
* Raphael from the ''Franchise/SoulSeries'' is a left-handed fencer, so that his face and chest can face the screen like the rest of the (right-handed) cast when picked as player one's character. Then again, as the games progress this ventures into ASinisterClue territory...
* [[spoiler: Knight Artorias]] from ''VideoGame/DarkSoulsI'' is implied to be one by the description of his greatsword in [[VideoGame/DarkSoulsII the sequel]][[note]](and that you gain some of his moveset when the sword is equipped in ''your'' left hand.)[[/note]], despite fighting you with his right hand when you encounter him. This is because [[spoiler: his left arm was [[DramaPreservingHandicap mangled and rendered limp]] while protecting Sif from the Abyss.]]
* ''VideoGame/SuperSmashBros 4'' casts VideoGame/{{Mega Man|Classic}} as a lefty, due to his AmbidextrousSprite in his source series shooting with his far arm -- which, in a left-to-right platform game, was usually his left. Granted, ''Smash Bros. 4'' also uses Ambidextrous Sprites, but in his Final Smash sequence, he summons protagonists from four other ''Mega Man'' series for a joint attack, and of them, only [[VideoGame/MegaManBattleNetwork MegaMan.EXE]] [[ShownTheirWork shoots with his right arm]].
* In ''VideoGame/MarioGolf'', any character can be lefty by pressing the L button on the character select screen. This is useful if a character has a fade or draw and you want their shots to curve the other way.
* FightingGame characters (particularly in 2D games) who fight with their back to the screen can be implied to be fighting southpaw, as typically characters will lead with the hand that correlates to the side of the screen they're on (so on player 1's side, the character will lead with their left hand and player 2 with their right, as long as they face the screen). Examples include Lin from ''VideoGame/TheKingOfFighters 2000'' and Tusk from ''VideoGame/KillerInstinct 2''.
* The Space Marine from ''Videogame/{{Doom}}'' uses his left hand for pistols and punching. That said, he uses two-handed guns like a righty would.
* In ''VideoGame/PunchOut'', Soda Popinski is a lefty, making him a bit harder to read than the other opponents.
* In ''VideoGame/UnderNightInBirth'', LadyOfWar Orie wields her sword with her left hand, and so does Yuzuriha, the local IaijutsuPractitioner, holding the sheath of her sword with her right hand, and drawing with het left hand.
* In ''VideoGame/EternalFighterZero'', Mai Kawasumi, another IaijutsuPractitioner, is a lefty: she holds the sheath of her sword with her right hand, so she can use her left hand to draw.
* ''VideoGame/DayOfTheTentacle'' - Ned and Jed, identical twins whose only differ lies in their handedness preference. In order to bypass Nurse Edna, who is guarding the video feed in the present, Hoagie (stuck 200 years in the past) has to switch the two twins while they are making a statue so that said statue flips in the present day, allowing Bernard to push Edna down the stairs without her being able to rely on the statue to right herself.

[[folder:Visual Novels]]
* Haruka of ''VisualNovel/LittleBusters'' is left-handed. It comes up while they're setting her up for the baseball team and they briefly discuss the way she has a small advantage because of it. [[spoiler:It wasn't so advantageous when her BigScrewedUpFamily assumed left-handedness was a sign of weakness and beat her for it, though.]]
* ''VisualNovel/{{Kanon}}'': At one point, Yuichi and Ayu bump into each other because the former tells the latter to jump at the side where she holds her chopsticks. Due to her being left-handed, their crash cannot be avoided.

[[folder:Western Animation]]
* Downplayed with Doug, in Nickelodeon's ''WesternAnimation/{{Doug}}''. It was only occasionally a plot point, such as when his friends couldn't figure out why he was such a poor beet-ball player until they realized they had been trying to make him bat right-handed. It shows up again in another episode where his much-beloved journal goes missing. No one can read it, partly because of his poor handwriting, but also because as a lefty, he drags his hand through everything he writes, leaving it a smudged mess.
* WesternAnimation/SpongeBobSquarePants is said to be left-handed in several episodes (in Neptune's Spatula he had two left hands) and in several others he says he's ambidextrous, but he can be seen using his left hand more often than not.
* In ''WesternAnimation/TheSimpsons'', Bart Simpson is left-handed, as he is based on the show's creator Matt Groening. Marge Simpson and Ned Flanders share this trait, among others--Marge was afraid of being seen as weird for being left-handed, so she taught herself to use her right hand instead, but eventually admitted that she's been better with her left hand.
* Finn the Human and Marceline the Vampire Queen from ''WesternAnimation/AdventureTime'', too.
* Tina of ''WesternAnimation/BobsBurgers'' is the only left-handed person in her family.
* WordOfGod says Phineas from WesternAnimation/PhineasAndFerb is left-handed. He appears to be ambidextrous, as he can write and play various instruments with both hands. However, he does seem to lead more with his left hand than his right, as he plays a left-handed drum set, uses left-handed tools, and bats left-handed in baseball.
* In ''WesternAnimation/{{Rugrats}}'', Chuckie Finster at first was like the other members of the Rugrats gang until one episode established that he was becoming left-handed. And he continued on as this through WesternAnimation/AllGrownUp, though at the time, it's not so much of a plot point anymore.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Ponies are mostly ambidextrous, but Fluttershy in particular often seems to favor her left hoof and wing when performing complex tasks. Her human self from the ''WesternAnimation/MyLittlePonyEquestriaGirls'' universe confirms this by nature of actually having hands.
** [[http://persona22.deviantart.com/art/Trixe-the-Left-Hoofed-Unicorn-466023778 Trixie is lefty as well]], supported by the main show and the second movie.
** To contrast with pony Twilight Sparkle who writes with her right hand when turned into a human, the human Twilight Sparkle writes with her left hand.
* It's subtle, but in ''WesternAnimation/AdventuresOfTheGalaxyRangers'', Zachary is often drawn as using his blaster left-handed. It's quite prominent in "Trouble at Texton" where he's shown having to switch his blaster to his left hand to fire. Unfortunately for him, his left side is the one that had to be completely rebuilt with cyberware.
[[/folder]]

[[folder:Real Life]]
* The British Royal Family have a famously high precedence of left-handedness, but some members were reportedly forced from an early age to present as right-handed in public due to the archaic association of left-handedness with evilness or sin. Amongst those forced to change were Queen Victoria and George VI, with many citing it as a contributing factor to the latter's famous nervousness and stutter.
* For similar reasons to baseball, left-handed cricketers are very useful both with the bat and with the ball: for example, it is generally a good idea for a batting partnership to consist of a right-hander and a left-hander, to put bowlers off their line and tire the fielders when the batsmen cross.
** Australian bowler Bill O'Reilly (no, not [[Creator/BillOReilly that one]]) hated bowling to left-handers and said they should be drowned at birth. A leg spinner is essentially an off spinner against a left-handed batsman, as the ball spins towards them instead of away.
* Racket sports, and tennis in particular, often have an advantage attributed to left-handed players. A good tactic in rallies is to hit to the opponent's backhand as it is (usually) weaker than the forehand. Of course, a left hander's backhand side is the opposite to a right hander's. Add this to the fact that rallies usually involve more cross court shots than down-the-line, and you can easily end up stuck in a situation where you are playing from the backhand straight into the opponent's forehand every time. Plus, when receiving serve the spin of a left hander's serve goes in the opposite direction to a right hander's, often making for some unpredictable and hard to return serves.
* Averted in golf, though. Since golf is (if you'll excuse the terms) PlayerVersusEnvironment rather than PlayerVersusPlayer, and the slopes of most golf courses are designed for right-handers, there are relatively few left-handed golfers at the highest level (although Phil Mickelson and Mike Weir are two relatively recent left-handed major winners).
* Left-handed auto racers in left-hand-drive cars benefit greatly from keeping their dominant hand on the wheel while shifting gears. Averted by the more modern UsefulNotes/FormulaOne steering-wheel controls which use the left hand to shift down and the right hand to shift up without ever letting go of the wheel.
** Left-handed drivers in right-hand-drive cars can shift gears effectively if learned correctly. Since the steering wheel and the driver seat are on the right side, and the DrivingStick (or any other type of transmissions) is on the left side of the driver's seat, it requires a left hand to shift the gears, thus southpaw drivers could learn it more effectively compared to righties.
* In late antiquity/early medieval warfare, a common trick (the Saxons and maybe the Normans made good use of this) was to fight as though left handed, thus minimizing the enemies' shields and throwing them off.
* Left-handed bowlers can be seen as having a significant advantage over right-handed bowlers. Since most bowlers bowl right-handed, they're all throwing their ball along roughly the same path as each other, which can throw off the oil pattern significantly. Left-handed bowlers generally have fresh oil, since few people bowl along the left side of the lane, and are thus able to get a much more consistent shot. Having a fresh oil track on the lane is a very good thing, as it allows the ball to travel faster, and with more spin, meaning that the pins can be stuck harder, and allowing for greater control of the curve, which is essential in getting a strike, since the best way to get a strike is to hit the pins behind the first pin, with the ball curving slightly to the center of the cluster, so that the pins hit each other in a mushrooming pattern.
* One defense used in medieval castles was to make spiral staircases twist clockwise as they went up so that a right handed defender's body was shielded by the center wall. This made left handed troops a valuable resource when trying to storm such castles. In fact, two Scottish castles (Eilean Donan and Ferniherst) have anti-clockwise staircases for the advantage of left-handed defenders.
* Swordplay. In general you are encouraged to fight from your good side for the obvious advantages in free fights (but also because it is a pain to fight from your weak side - or to re-train your good side when you started learning on the wrong side). Once you get used to how to attack a right handed opponent on his left (vulnerable) shoulder when your opening position has the sword on your left shoulder it is no big deal anymore. (However most lefties also learn to do at least the basic moves also from the right side. Which is of high advantage when your opponent finally got used to you being a leftie and adjusts his attacks so you can attack him from the right. The other main advantage in general is that due to most people being right-handed, both lefties and righties primarily train to fight against righties. Matt Easton of WebVideo/ScholaGladiatoria, who is right handed, actually turns this to his advantage in [[https://www.youtube.com/watch?v=o8XIDdPRx04 this video]]. This trope also applies to fencing; lefties are MUCH harder to hit if you're used to fighting righties due to the fact that you have to hit the opposite side of their body. In [[DuelingScar academic fencing]], normally only one side of the face is a legal hit zone. In the rare cases of left-right matchups, both sides are exposed which greatly increases the risk of getting hit for the right-handed fencer, since he is often not trained against southpaws.
* There exists a beer company in Colorado named "[[http://www.lefthandbrewing.com Left Hand]]". They produce [[AccidentalPun sinister]] brews.
* The [[SemperFi United States Marines]] have found that shooting a bolt action rifle southpaw allows a sniper to shoot slightly faster; the bolt on the [=M40A3=] is on the right, meaning that a right-handed shooter would have to remove his hand from the grip and trigger, work the bolt, and return to firing position. A left-handed shooter can keep his eye on target and his left hand by the trigger and work the bolt with his right hand (especially since for long-range shooting, you're not going to be supporting the rifle with just your off-hand); as the firing hand does not leave the trigger, the interval between firing is reduced.
* TiedUpOnThePhone: One of the inevitable results of old-style telephone receivers, where the handset was permanently attached to the receiver by a coiled cord, was how quickly the connecting cord ceased to be a neatly organised smooth coil. It would inevitably tangle, snag, knot, loop back on itself, and tended to somehow double over on itself, until the connecting wire between handset and receiver was effectively half its original length. Anyone picking up the handset to such a phone would drag the whole thing up off its table and find it swinging in the air. Left-handed users soon found that the arrangement favoured right-handed people - both in the direction of coiling, and in the way the headset was meant to be returned to its rest with the connecting wire on the right-hand side. Any old-style phone regularly used by left-handed people would unravel its coils twice as fast (the natural tendency being for a left-hander to return the handset to the rest with the coil-connected end on the ''left''.) Any household with both left and right handed people would discover their shared phone suffered from Garden Hose Syndrome - it became an utter tangled mess very quickly.
* UsefulNotes/{{NHL}}:
** A large number of players learn to shoot left-handed even if they aren't natural lefties. If they find themselves in a situation sprinting or otherwise only holding their stick with one hand, it ends up being in their dominant right giving them more control. More importantly though, is shooting angles. Generally left-handed shooters will play the left wing and righties will play the right wing although it's not a hard rule and sometimes a coach will flip them depending on how he wants a play set up. It's also just a good idea to be able to handle both directions since sticks frequently break in the middle of play. If that happens your option is skate to the bench and grab one from a teammate so you can get back in quickly and it's not always going to face the way yours normally does.
** Most goalies catch with their left hand and hold their stick in their right but some do the opposite and the opposing team generally has to use a different scoring strategy against them because the types of shot a left-winger might normally take on the blocker side won't be as effective if the goalie has his glove on that side (and vice versa).
* For soldiers, law enforcement, and other such lines of work, being able to shoot using either hand adds versatility to the positions one can fire from. If exposing the smallest portion of your body to return fire requires switching hands to take better advantage of available cover, then so be it. And if injury or other circumstances make it difficult to favor one's dominant hand, being able to continue fighting while relying on the offhand can come in handy.
* Left-handed arm wrestlers have a much easier time against right handed ones due to the fact that "righties" often neglect their southpaw.
* Thoroughly averted in the world of power tools. Almost all of them are designed for people favoring the right hand, and using them in the left can be awkward at best, and extremely dangerous at worst. Probably the worst example is lawn edgers or weedeaters, since, by their nature, they fling rocks, dirt clods, and other debris out from them, and, for left handed users, the guard is located ''on the wrong side''.
* Video game controllers:
** Controllers designed for left-handed people are also rare to nonexistent, as the companies that make such things know that lefties make up no more than 10% of the potential market. This problem is at its worst for advanced controllers such as flight sticks.
** The Wii remote and nunchuck avert this problem, as both are symmetrical. However, some games that rely on advanced gyroscope controls, such as ''VideoGame/TheLegendOfZeldaSkywardSword'' [[note]]ironically, Link was canonically left-handed in the earlier games[[/note]], have this problem as the software expects the nunchuck on the left and remote on the right.
** Also averted by the AtariLynx. Unlike all other handheld game systems, the [=Lynx=] could be rotated for either left- or right-handed use.
* Similar to fencing, left-handed boxers are considered at an advantage as boxers are more accustomed to fighting against opponents who favour their right hand. In boxing posing yourself to jab fast with the right and hit hard on the left is called "southpaw stance".
* Also applies to animals: [[http://news.nationalgeographic.com/2015/06/150618-kangaroos-evolution-animals-science/ Majority of the kangaroos are left-pawed.]] Beware if you see, or dealing with a BoxingKangaroo.
* Modern U.S. presidents from H.W. Bush to Obama are noted for this, with 3 out of 4 having a dominant left hand. Ronald Reagan is ambidextrous, and indicated he was naturally left-handed but forced to switch, making it 4 out of 5 if counting him. George H.W. Bush, Bill Clinton, and Barack Obama are all lefties, while George W. Bush is righty.
