Many fans have poked fun of Johnny being Jonathan's alternate universe counterpart, as the two couldn't be more different, with Jonathan being a big muscular Englishman with an honorable and gentle demeanor, while Johnny is a small, frail cowboy with a sarcastic streak and violent tendencies.
Also, "the Jonathan without a Stand vs. the Jonathan who can't stand" and "Johnny can't 「STAND PROUD」!".
Johnny can't use the Joestar family secret technique!ExplanationThe Joestar family's "secret technique" is running away from a fight, which Johnny can't do because he's in a wheelchair.
Johnny is THICC. ExplanationFans have joked about Johnny being drawn in the manga with well-toned buttocks. This has raised questions on how Johnny has such a physique if he is paralyzed, with some suggesting that Johnny is actually wearing an adult diaper due to his incontinence.
Using "Jesus mummified steel ball Christ!" (and variants) as an epithet. ExplanationThe Corpse Parts (of part VII) are heavily implied/outright stated to be the body of Jesus Himself; referencing this when taking His name in vain was only natural.
"EAT SHIT, ASSHOLE! FALL OFF YOUR HORSE!" ExplanationA Funny Moment from Gyro Zeppeli. The panel (and the proceeding one, where he tells Johnny to say it, and Johnny says, "Tell him yourself,") are sometimes used as reaction images in response to someone saying that they don't like JoJo's Bizarre Adventure.
Jesus was the original JoJo. ExplanationJesus of Nazareth plays a prominent role in the plot of Part 7, and historians estimate that his Hebrew name was likely Yeshua bar Yosef, or "Joshua, son of Joseph." Fans quickly latched onto this, stating that this technically makes Jesus a JoJo.
Dino Brando/DiosaurExplanationDiego Brando acquires the Stand Scary Monsters, which grants him the ability to turn into a raptor-like dinosaur. The pun potential was not lost on fans.
Fans have joked about a scene where Johnny yells "Open the door! Get on the floor!" while being attacked by Diego in his dinosaur form, due to those two lines being in the chorus of the song "Everybody Walk the Dinosaur" by Was Not Was.
With the Science Marches On discovery that Velociraptor possessed feathers, quite a number of fans have tried redesigning Diego's raptor form to have plumage, as well as other characters reacting to the feathered Diego.
"Doyjaaan" ExplanationFunny Valentine's Catchphrase, roughly meaning "Ta daa".
Some fans have joked that Gyro's horse Valkyrie is actually the alt-universe counterpart of Prosciutto, due to them having a similar hairstyle of a row of small buns on the back of their head.
Filthy Acts at a Reasonable Price. ExplanationAnother casualty of the series' Writing Around Trademarks problems, where Dirty Deeds Done Dirt Cheap's name got butchered in JoJo's Bizarre Adventure: All Star Battle. Although early screenshots implied that Valentine's Stand name would be kept as D4C (Dirty Deeds Done Dirt Cheap), jokes of this sort abounded — and then "Filthy Acts at a Reasonable Price" 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. As a result, many fans will make verbose, awkward, and occasionally alliterative Engrish-y "translations", such as "Awful Actions at an Affordable Amount," especially considering you can hear Valentine say his Stand's proper name in English in the game.
FA3RPexplanationAn abbreviation of "Filthy Acts at a Reasonable Price" in the same way that "Dirty Deeds Done Dirt Cheap" is abbreviated to "D4C".
D4C Pain Train! ExplanationA pun of D4C Love Train. This also is what experienced purely-offensive Funny Valentine players are referred to as.
D4C's ability to access parallel universes has been joked about the fandom, claiming that it makes every single AU technically canon, in a similar vein to "as long as Diavolo dies it's canon".
Valentine's ability to bring other, parallel-universe versions of existing characters are also joked about the fandom as being very different from their main-universe ones, such as an intelligent Okuyasu or a Jotaro who respects his mom.
All rise for the national anthemnote D4C's namesake song is often used as a replacement for the actual national anthem, seeing that its owner is the American president. This often comes up around American Independence Day
"Old Town Road" is a popular joke prediction for the hypothetical anime adaptation's ED.
"Ram Ranch" is also associated with Steel Ball Run with varying degrees of irony due to Ho Yay between Johnny and Gyro.
Funny Valentine did nothing wrong.ExplanationA cheeky joke in the same vein as "Hitler did nothing wrong", referring to how beloved Valentine is both in-universe and with readers due to his charismatic nature and how his goal of acquiring the corpse parts seem to be noble, at least on a surface level. It doesn't literally mean he didn't do anything wrong, as any honest fans can point to his many misdeeds, just a silly way to brush off his villainous acts being committed for the greater good of his country.
Valentine's speech about taking the first napkin has become a popular copypasta due to its Mundane Made Awesome nature.
Tusk Act 4, spin his balls! ExplanationAs the meme of the Mage of Testicular Torsion spreads and develops new variants, there are multiple edits, memes, and comments seemingly establishing "Johnny commands Tusk Act 4" as the de facto Jojo edition of the meme.
