Rated M for Mara!Explanation Mara, basically Gag Penis in summon form, is a recurring Persona in the series, and often believed to be the reason behind the series' M rating in America. It isn't, but it still tends to be brought up in discussions of any Persona game's rating.
DIDJA SEE THAT SHINJI!? Explanation Akihiko's victory cry. It is actually really sad, since he starts using it only after Shinjiro dies.
"Summon your persona" has become an Unusual Euphemism for suicide, since you summon personas in this game via miming the action of shooting yourself in the head (the Evokers aren't real guns, but suicidal ideation seems to be important for bringing out your Persona somehow). And in fact, the first time you see Yukari, she's trying to summon hers and it looks like she's about to kill herself.
"I'm dying Mitsuru." "MARIN FUCKING KARIN." " :< " "Death is not a hunter unbeknownst to its prey..."Explanation Mitsuru will often use Marin Karin (a spell which sometimes (read: almost never) inflicts Charm status on enemy) instead of something more appropriate.
It's like I'm really Japanese!Explanation Used to mock the gratuitous Japanese used in the English localization. Can be used to mock any claims of realism a game has (e.g. "It's like I'm really committing crimes!" for Grand Theft Auto).
Shota shortsExplanation Elementary-aged Ken Amada always wears short shorts, even during the winter. Naturally, this got a nickname.
"BUUUUUUUURRRRRRN MYYYYYY BREAAAAAAADDDDD!" Explanation A rather infamous Mondegreen.
Also known as "BUUUUUUUUUUURRRRNNNNN MAAAAADRIIIIIIIID".
"BITCHES AND WHORES." Explanation Adachi turns out to be one hell of a misogynistic scumbag when you confront him as the real killer. From a 4chan edit of a Rise hentai doujinshi. Has become an Ascended Meme in the anime with Adachi actually saying this line.
I find the above meme bear-ly bear-able. Explanation Teddie's dedication to bad puns is endless.
"I'm gonna RENOVATE your ass!" Explanation This comes from one of Kanji's anger fits. He threatens to tear down the resteraunt he and MC are eating at. When he realizes he's relapsing when he said he was going to try and be nicer he adds, "I'm going to tear it down... and the build it twice as good! I'm gonna RENOVATE your ass!"
"I am a shadow...the true self." Explanation Every Shadow boss says these words at the start of their fight.
Spoiler alert: Teddie ate five Topsicles!Explanation From Feinne's LP of the game on the Something Awful forums.
Tohru Adachi: A young Inaba-PD detective. He's buddy in your uncle Dojima.Explanation (Spoilers) From a fan hack that had Adachi as the Aeon Social Link. Possibly an Ascended Meme, as he has a Social Link in the remake: The Jester Link. Or rather, the Hunger link.
Peachi's series of Persona 4 comics have spawned an army of memes, including:
Shut up. It's an endearing character trait. Explanation This line, uttered by the narrator when seeing Yukiko's laughing fit for the first time, became attached to Yukiko in many many fanworks related to her laughing.
"I HAVE TO PEEEEEE!!" "YOU GUYS! I HAVE TO PEE, SO BAD! I'M GONNA PEE, RIGHT. HERE! ..... Okay never mind." Explanation Yosuke and his peeing problems.
I hope you're beary prebeared for this unbearablebear of a battle! Explanation Teddie has a tendency to make a lot of bear puns.
SOUNDS LIKE SOMEONE JUST ORDERED A STUPID LOOKING BOSS!!
"RISE END CONFIRMED!" "YOUSUKE END CONFIRMED!"Explanation The first one comes after episode 9 and 10, which is full to the brim of Rise/MC Ship Tease. The second comes in episode 12, in which Yousuke and the MC start going by First Name Basis in a scene that's simply dripping with Ho Yay. Naturally, 4chan had a field day.
"BROTAG WILL GET EVERYONE LAID."Explanation After episode 15 (which shows the infamous field trip and the love hotel scene), the MC became a full-fledged Memetic Sex God. 4chan had another field day.
Cabbage Explanation A meme that started in Japan. Was originally a line in one scene where Adachi says he only has enough money to buy cabbage. Fandom later decided to make it his Trademark Favorite Food. With the release of the anime, it now has become an Ascended Meme.
Meat DimensionExplanation At the Chinese diner Aiya on rainy days, you can take on a challenge involving eating a very large beef rice bowl. At one point, the game describes the bowl as you suspecting that the bowl is a "portal to the Meat Dimension".
Even in my Persona games, F.O.E. Explanation Persona Q is Etrian Odyssey reskinned with the P3 and P4 characters, and it includes the infamous overpowered F.O.E. (See the sole Etrian Odyssey meme)
THIS CAROUSEEEL!!!!! Explanation Go to any Persona Q stream and see how many referances to carousels are made due to the theme song.
Shinj's right there, Akihiko. Explanation An extention of the "Didja see that Shinji" meme above, due to Shinjiro being playable alongside Akihiko again, a lot of commenters bring up the original line and give it a much less tragic context.
You are slave. Want emancipation?Explanation The first teaser for Persona 5 was a picture of five chairs that were "held down" with prison weights, and had this line of Engrish text to go along with it. Oddly enough, the only localization change to the tagline was to add an a before "slave".
Tuxedo Mask/Naruto/Junko Enoshima comfirmed.Explanation With the release of the second teaser, many people noticed that the Protagonist's 'Phantom' form looked quite a bit like Tuxedo Mask, Ryuji (the blonde haired boy) looked like Naruto, and Anne (the blonde haired girl) looked like Junko Enoshima.
Alternately, people have been calling the protagonist "Vincent" and Anzu "Catherine."
