SOON. Explanation Ever since the very first concept art was posted Animation Do's home page, that picture was posted pretty much every single day (sometimes even multiple times a day) on /a/ for over a whole year until the first animated commercial happened. The picture was always posted together with only one word - "SOON".
The show called "the fastest growing tumblr fandom"
In addition to the nickname "Swimming Anime", there's also "Swimming Yaoi" due to the presumed homoeroticism the show will have.
Other nicknames include "Swimbros" and "Boku no Swimbros", the latter being a reference to the infamous (not to mention Memetic) Shotacon hentai series Boku no Pico.
Don't call her Gou/Her name is Kou. Explanation Rin's sister dislikes her masculine-sounding name "Gou" and prefer the more feminine way her name can be read, "Kou". So naturally, if someone refers to her as Gou, it has to be corrected.
Another overlap with the Attack on Titan memes includes Shingeki no Shitstorm, a video meant to serve as a Take That to the anti-fujoshi Hatedom that appeared in response to Free! and its growing fandom of yaoi fangirls.
Related to the 'drowning anime' predictions, many also started guessing that the anime would turn into Puella Magi Madoka Magica.
Nagisa dies. Explanation with HUGE spoilers for CLANNAD ~After Story~ A crossover meme with CLANNAD ~After Story~, since both shows 1) are made by Kyo Ani and 2) feature a character named Nagisa, and everybody who watched CLANNAD ~After Story~ knows that, well...
Nagisa does drugs. note To some, this is the initial reaction to his "purifying salt" from episode 1; since then, the scene has spawned several jokes revolving Nagisa and drugs.
Haruka's obsession with water and stripping whenever he sees a pool/Haruka is H2Osexual Explanation After episode 1, Haruka X Water jokes exploded across the Free!dom, mostly involving Haruka stripping at the mere sight of water, being attracted to water, etc, etc. It only got worse after episode 2 showed him seriously considering climbing into a fish tank at a hardware store. He admitted that he fell in love with a waterfall when he was younger.
"When you're ten, they call you a prodigy. When you're fifteen, they call you a genius. Once you hit twenty, you're just an ordinary person." (Repeated on Tumblr ad infinitum)
Megane Makoto!! note Makoto with glasses got instantly popular after the ED art for episode 4
Depicting Rin as being secretly protective of Kou and being angry about her being around a bunch of topless bachelors all the time is quite common amongst fan artists.
Why the FUCK do you relate this show to ours?◊ note It's a well-known fact that Free! and Attack on Titan have Friendly Fandoms, and it's also well known that their tones couldn't be more different. The gif was one that made its way around the internet via a tumblr post with the caption, "Nagisa and Makoto watch Attack on Titan and wonder why the FUCK you relate this show to theirs."
Rin's Australian Accentnote Considering that Rin lived in Australia for approximately three years, it has become very common to depict him with an Australian accent when speaking English in fanworks.
