More to the point, it's because Shirou doesn't. The Fate route has Shirou take mortal injuries at least six times, including being disemboweled, stabbed through the heart, and cut clean through from shoulder to hip, and his Healing Factor keeps him alive. He says this as he decides to give that power up so Saber can use it to stand a chance against Gilgamesh. What he was actually saying is that people are supposed to die when they're killed, so losing the power isn't a problem. Doesn't stop people from making fun of Shirou for this though.
"Alright, Shirou! Please put your... that! Y... Your pOnOs! To my... my... Here! .....My vagOOO!!! And J.. J... JAM IT IN!" Explanation A series of Fate/stay night parody comics makes it a Running Gag that Shirou frequently suffers Entendre Failure when faced with sexual innuendo, and one doujinshi in particular portrays him as ignorant of even basic understanding of the mechanics of sex, requiring this line from Saber. The O's in the words "penis" and "vagina" are supposed to be circles representing blank-space censorship.
"...you lost me." Explanation A fancomic by Veloxiraptor, created as a parody/response to the above, has Shirou say this line in response to Rin and Saber trying to teach him how to perform the act.
1. Put pOnOs (A) to vagOOO (B). 2. JAM IT IN! 3. ????? 4. PROFIT!!!
LOL dragons. / LOL dolphins.Explanation Remember how Fate/stay night origins comes from a eroge of the same name and how the anime adaptions of its storylines happens to have Bleached Underpants. This is how, during two obvious sex scenes... before anything risque shows up, you are treated to a show of a CGI dragon (in the anime) or CGI dolphins (in the movie) instead of the scene.
Mana Transfer Dragon, the one used for Saber's scene in the anime, now has its own tag on Danbooru and similar sites.
I am gar for Archer. Explanation Someone misspelled "I am gay for Archer." and the misspelling stuck.
Fill-in-the-blank Archer version:Expand I am the bone of my sword. Steel is my body, and fire is my blood. I have created over a thousand blades. Unknown to Death, nor known to Life. Have withstood pain to create many weapons. Yet, those hands will never hold anything. So, as I pray, Unlimited Blade Works.
Fill-in-the-blank Shirou version:Expand I am the bone of my sword. Steel is my body, and fire is my blood. I have created over a thousand blades. Unaware of loss, nor aware of gain. Withstood pain to create weapons, waiting for one's arrival. I have no regrets. This is my only path. My whole life was Unlimited Blade Works.
Unlimited Essay Works.◊ Explanation An anon claimed that he turned in a page for his final paper of a writing class he was flunking using an altered UBW chant.
Did you mean "Bane"?
"I ask of you: Are you my Master?" Explanation This is mainly the first line EVERY servant states when they are summoned in ALL Fate series. Most notable during Saber's summoning in Fate/stay night and Fate/Zero.
"This is a war which mucks around with women and children!" Explanation In the Fifth Holy Grail War, there were 6 children MASTERS and three female Servants in the this war; it was severely invoked by Gilgamesh.
Being Lancer is suffering. Explanation The Lancer class has "E-Rank"Luck Stat; and this presents itself story-wise as them being horribly shafted. Borrows from Puella Magi Madoka Magica. Surprisingly enough, more than a half of Servants that make appearence in Nasuverse has the same rank in Luck, with only few exceptions like Saber or Aleksander the Great
Mongrels! Those swords are fucking patented! Explanation A flanderization of Gilgamesh's interaction with Shirou and Archer. Brought up in the Character Development Cliff Notes style of the Unlimited Blade Works route.
Yuetsu!! Explanation The Japanese word for "pleasure", alternatively translated as "joy" or "entertainment"; one of the plotlines involves Gilgamesh making Kirei realize what exactly the source of these things is for him. It's probably a result of the frequent use and the Ho Yay that comes with it that made it into a memetic word among the fandom.
Ancient Hindu Spaceships! Explanation Mutated form of the Yu-Gi-Oh! The Abridged Series Ancient Egyptian Laser Beams meme when referring to Gilgamesh's flying ship in Fate/Zero. Yes, it's at least grounded in true myth in the Ramayana.
Happy Mother/Father/Children's Day, Kiritsugu!Explanation Fate/Zero had episodes that aired on Mother's Day, Father's Day, and Japan's Children's Day. In said episodes, Kiritsugu is forced to kill his adoptive mother, (Grail-created versions of) his family, and his childhood friend respectively
UNLIMITED BUDGET WORKSExplanation With Ufatable also adapting the full-length UBW anime and also piggybacking off of the immense financial success of Fate/Zero, the animation in UBW was set to be very, very well funded.
It's shit. Explanation Infamous reaction image from Hiroyuki (again). Specifically, from Shiki looking at an image Ciel is holding that says "Curry + Ass" (referring to her anal scene), but he interprets it as the end result of the digestive system. Nrvnsqr does too for whatever reason.
"There is noTsukihime anime."◊ Explanation The anime is widely considered to be an example of Adaptation Decay, and complaints are often to the point of wishing it had never been made. While reviewing the anime, Arkada also said, "This anime doesn't exist. In the same way that some movie sequels and prequels don't exist, this show doesn't exist."
"Rape the maids." Explanation Standard response to the question, "You wake up as Shiki. What do you do?" Mainly stems from a specific choice in the Ciel route where the game interprets "send Kohaku away with your dinner because you don't feel well" into "rape her".
Brainwashing Detective Hisui-chan. Explanation One typo from a Bad Ending (Anata wo hannin desu - You become the criminal. The original line is Anata wa hannin desu - You are the criminal.) lead to the creation of this Fan Nickname.
PORN WITH PLOT. Explanation An old derogatory exclamation that has evolved to refer to eroge and visual novels in general.
SUGOI SUGOI! Explanation Fanon states this as Aoko's catch phrase. It comes from Melty Blood where one of her attacks has her shouting this. And of course the attack is very spammable, resulting in her shouting "Sugoi Sugoi" over and over.
Shiki Tohno: Lord of Bedroom Jackassery. Explanation Shiki is a more or less kind dude and relatively well-adjusted despite his sucky life... but he is NOT the gentlest lover in bed. Arcueid? He's far too rough. Ciel? He pressures her into anal though she's not that willing. Akiha? He's a Jerk Ass to her. Hisui? He behaves better but still teases her too much. Kohaku? He wises up but only after their first sex scene.
