The infamous "DUWANG" Translation Trainwreck of part 4 has brought some memorable lines such as "Get a feeling so complicated...", "Who in FACE are you?!" and "What a beautiful Duwang". The improved translations in the making keep a few of those as in-jokes and the TV anime is even being "translated" in this style by one fansub group.
Whenever an argument about who would beat whom in a fight comes up, the answer is always Giorno. Along with The Flash, he's perhaps the person most commonly brought up in power level debates.
The series' distinctive art style has become a meme, being a popular choice for Art Shifted fanart of other series.
Similarly, if someone randomly throws around the Japanese "dramatic tension" Unsound Effects ゴゴゴゴゴ (GO GO GO GO GO) and ドドドドド (DO DO DO DO DO), it's guaranteed to be a JoJo reference.
"Out of Function/Retire(再起不能/リタイア)"note The words that are used in narration as the status of the villains who were defeated by heroes, but end up alive or worse.
Araki's habit of drawing the characters in very weird poses, such as Diavolo's final pose (when he's running from the little girl), Giorno's "gang-star" pose, and Anasui's model-esque◊ pose, has also spawned some memes.
The infamous anatomy description that appears for Kars when he becomes the Ultimate Being. Partly because it's reminiscent of many a bad DeviantArtGary Stu, but especially for one stand-out entry pointing out that for Kars, "Sex:USELESS".
People being confused about how King Crimson works will often result in everyone saying no one knows how it works.
"It just works."
YA YA YE COCO JUMBO YA YA YE note The Stand turtle in Part 5 is named after a rather disturbingly Ear Wormysong which many assume plays nonstop for anyone inside the turtle.
Fans have noted a fair number of coincidental similarities between Part 2 and the movie Zoolander (if Joseph is Derek). The main character's lack of common sense in many areas, the rivalry between Joseph/Derek and the new blonde ripple user/model that comes on to the scene, the large emphasis on posing, the odd fact that some scenes just look familiar, and the fact that both characters had their friends killed by Wamuu.
"Giant bara deer": A term for the musclebound men in the first parts of JoJo that arose after this animated .gif of Jonathan◊ appeared on /a/ with the filename "giant_bara_deer_caught_in_headlights.gif".
Calling Wamuu's Holy Sandstorm attack the "Holy Wubstorm", after the Pillar Men's dubstepleitmotif.
Esidisi's crying face.
Rohan's response of "But I refusenote Common fan translation/Like hell I will!note ASB translation/Daga kotowarunote Romanji/だが断る" when Highway Star commands him to call Josuke for help and thus lead him into a trap, is also a popular meme in the Japanese community, applied to any less than stellar Jojo-related info, product or news, or even anything in general. Ironically, Rohan uses this line and claims that he likes to say "NO!" to the faces of people who think they're hot shit, despite Rohan himself fitting that bill a good deal. Its also seen as an act of badass on Rohan's part, as he was in mortal peril and an inch away from losing his life to Highway Star only to rudely deny Highway Star's demand anyhow.
AWAKEN, MY MASTERS!/MEZAMETAMAE, WAGA ARUJITACHI YO!/目覚めたまえッ！我が主たちよ!Explanation Wamuu shouts this line when waking up two Pillar Men, Kars and Esidisi. What makes this moment is both Akio Ohtsuka's delivery of said line and the FABULOUS poses the three Pillar Men take once they're awakened, the fact that Wamuu awakens them by making his own fabulous pose while poking their cheeks with his fingers, and in the anime, the dubstep-laden music (fittingly titled "Awake") playing over it.
Ahh! Sto-sama is dead!/あーん!スト様が死んだ! Explanation with mild spoilers for Battle Tendency Japanese meme taken from a fan-submitted picture of the slightly unhinged artist bawling on Straizo's chest at the end of the volume in which he dies. Likely kicked off because of the hilarious FangirlSelf Insert going on, and goes to show you that Estrogen Brigades as we know it (and the Draco in Leather Pants aspect of Fan Dumb for that matter) predate the Internet by a loooooong shot.
"The first time I saw her, with her hands on her knee... how do I say this... I had a boner..."Explanation Another Duwang classic that is rapidly gaining steam: A delirious and badly beaten Yoshikage Kira explains to a random woman about how he got an erection just from looking at the Mona Lisa, which is why he kills women and takes their severed hands as "girlfriends." Even crazier is how, despite sounding like a product of the notoriously shoddy translation quality of Duwang, it's quite accurate to the original Japanese. The original panel even has the kanji for "erection" and crude speech patterns inside of that very same speech bubble.
"Your stand is like your asshole. You can't go around showing it off to other people." Explanation A vulgar analogy used by Norisuke IV while talking to Josuke/Gappy. It has been passed around on Tumblr to a dizzying extent.
"NANI WO SURUNDA!? YURUSAN!!!" Explanation Jonathan's surprise/shock when Dio kick his dog for no reason. Despite saying it only once as a kid it became his Catch Phrase and videogame taunt. It was used a lot on forums to show surprise/shock.
"DIOOOOOOOOO!!!" Explanation Said when Jonathan discovers Dio kissed Erina by force (and other times), and then fights with him. People usually make use of this quote when Dio appears or does something evil.
"You thought this would be [X], but it was I, Dio!" Explanation Another Dio classic. Originally, it was a boast to Erina about stealing her first kiss from Jonathan during the start of Phantom Blood. The phrase got so popular that it's used as a punchline for a Bait and Switch joke for just about everything, to the point that it's on the verge of becoming a Discredited Meme for many Jojo fans.
Diamond is Not Crazy Explanation A shorthand way of referring to the legal-dodging renames in the English version of All-Star Battle, in the shape of Part 4's Engrish-y name; specifically, to Josuke's Crazy Diamond having its name changed to Shining Diamond.
Also, Filthy Acts at a Reasonable Price. Explanation Although early screenshots implied that Valentine's Stand name would be kept as D4C (That is, Dirty Deeds Done Dirt Cheap), jokes of this sort abounded — and then it turned out to be the translation of his GHA attack. On top of that, the English version of his Stand info states that nobody knows what D4C is supposed to stand for.
Lastly, D4C Pain Train! Explanation A pun of D4C Love Train. This also is what experienced purely-offensive Funny Valentine players are referred to as.
How deep can I hit it? Balls deep! Explanation All Star Battle's Western localisation changes the usual translation of Jolyne's HHA speech, where she wraps a baseball with her string and rapidly flings it at her opponent, from "How many throws (of the ball) can I do in a row? A thousand!" to "How deep can I hit? Balls deep!".
With the TV anime premiere of Stardust Crusaders, it has become popular to swap out Dio's Hermit Purple-generated photo with just◊ about◊ anything◊ else◊.
Did something, anything, happen? Then shout, "This must be the work of an enemy Stand!", which seems to be the usual (and correct) assumption in Stardust Crusaders.
Shadow Jotaro Explanation The Stardust Crusaders anime covers Jotaro's mouth with a black circle whenever he smokes, probably because he is underage. Pic related.
"Diodidnothingwrong!" Explanation A tounge-in-cheek way of justifying the absolutely horrid acts Dio did, such as: "Danny attacked Dio first", or "Dio accidentally bought poison from Wang Chan thinking it was medicine and gave it to George".
Expect 「people」 who talk about Jojo to at least write a 「sentence」 with words closed by 「Japanese quotation marks」 and formatted in bold. Occasionally used to determine if someone has a 「Stand」.
Your next line will be: "[X]" ! Explanation Part 2 Joseph had a knack for predicting his opponent's next sentences. He always guessed correctly.
[X]! ... Uh!? Explanation The usual reaction from the above.
Because of a comment he made regarding his admiration of Jotaro's mother Holly, it's common on most sites to portray Noriaki Kakyoin has having a sexual preference for mothers.
The Eggbaby/"Kakyoin, did you lay this egg?" Explanation Reference to an early CLAMP doujinshi where Jotaro and Kakyoin are a married couple whose son came from an egg. Jokes and edits about characters laying eggs, being afraid of laying eggs, or coming from them abound. Meanwhile the original doujinshi is considered Snark Bait in the fandom due to the ludicrousness of the events portrayed as well as its lack of resemblance to the original characters either art-wise or personality-wise.
NO WEAKNESS Explanation Kira referring to his Killer Queen's secondary bomb - "Sheer Heart Attack... has NO WEAKNESS."
Araki's apparent hatred of dogs. Explanation In a pretty literal example of Kick the Dog, some poor canine has been killed by an antagonist in just about every arc: Dio puts Jonathan's dog Danny into an incinerator; dogs are killed by the Stands Yellow Temperance, Death 13, and Pet Shop's Horus (who kills two) in part 3, with Team Pet Iggy also dying in the finale; Starter Villain Angelo of part 4 bites off a dog's face, a wolf pup is shot by Magenta Magenta in part 7...The only notable exception is Kars, who saves a dog from getting run over in part 2; this further mutated into jokes about Kars being an extreme animal lover who is horrified by the other villains' actions.
"It's a Friday..." "Yes...finally here..." "Friday..." Explanation Born on Tumblr involving the release of a new episode of the Part 3 anime every Friday. Usually on that day is a reblog of the 3 panel comic of Joseph, Polnareff and Jotaro remarking on today being a Friday, said comic being a text edit of them remarking on having finally arrived in Egypt. There's also been edits poking fun at the meme as well.
Polnareff's Bizarre Adventure Explanation An observation about Stardust Crusaders that a lot of chapters focused more on Polnareff than the titular Jojos..
Jotaro's occupation as a Marine Biologist has lead many to imagine that Jotaro has an intense fondness for Dolphins. This has lead to much fanart and edits of Jotaro with Dolphins, or jokes that he is even zoophilic.
