John Freeman got on his motorcycle and said "its time for me to live up to my family name and face full life consequences"
The Invader Zim story "In Short Supply" features one in Chapter 29, when Red muses that "even for the Control Brains, information about Purple was in short supply." The title is actually supposed to be a pun on the Irkens' height-based society, though, and how Irkens of certain heights are much rarer than they should be.
The Firefly fic Forward drops its title at the end of the "Mosaic" story arc, with Mal telling River what direction they have to keep going in.
There is a subtle one in Kira Is Justice: When Justin decides to experiment with the Death Note, one of the victims yell out the words, "Kira is justice!" in a prison cafeteria before dropping dead. It is very amusing.
In the Sonic the Hedgehog fanfiction Created Equal, the speech Metal Sonic gave after Eggman's death:
"Flesh and blood have no purpose in this place. God made all men equal and men destroyed their gods. A man created me to be equal and I have destroyed that man. I laid waste to his empire of dust. Now I rule the empire of dust. And I will lay hands on that dust and create my own posterity. And I shall hold them to my single inglorious propositon; all robots are not Created Equal..."
In Fantendo: Playing War, before Sandslash transforms into Sandsmash and is consequently knocked out, Sunnyscythe utters "Let's play war...". There's actually a couple more of these, another by Sunnyscythe and yet another by Fantasma.
In the Star Trek fanseries Hidden Frontier, Commodore Cole drops the title of the show in the middle of a speech she gives in the sixth season premiere, as the blockade of starships is about to go into battle with the Tholians and the Breen who just started a war with the Federation.
There seemed to be [a] black turning funnel swirling across the landscape.
Hobbes does this in Part 2 as well. It's even capitalized.
"I was just thinking. Remember that dream I had this morning? It was about a funnel, remember? We actually saw and fought against a funnel! A Black Turning Funnel!"
From the end of "Two Loons and a Kid":
It was truly a magnificent day for the two loons and the kid.
From "The Case of the Rogue Water Balloon":
Calvin: Huh. I could have sworn we were on a very important mission...
Hobbes: I'm drawing a blank.
Calvin: NOW I remember! We were on The Case of the Rogue Water Balloon.
A rather poorly-done example - the oddly named "Nighty Shut Up!" only makes sense when you read this exchange:
"Okay," said Hobbes, and he left. "Nighty night."
"Nighty shut up." Calvin spat.
From "Mission: Socrates":
Calvin: Come on guys! Mission: Socrates is now in effect!
"With this power, I can do anything! I could easily do a Sonic Rainboom! Even a... Double Rainboom!"
"The longer you ignore your Inner Demons, the stronger they become."
The Kung Fu PandaFan FicA Different Lesson technically drops its title right with the opening blurb ("Can a father undo his past mistakes? Perhaps, if the snow leopard can be taught...A Different Lesson"), but it is properly referenced at least three times in the fic itself—the first time during the training on Wu Dan where it emphasizes what Tai Lung has to do differently and how he should view the world and his place in it if he wants to be a hero, the last time at the very end when he is reflecting back on everything he's gone through. The second time, in a sinister variation, is spoken by the Big Bad, implying what he will offer if Tai Lung joins him.
Since The Immortal Game was renamed halfway through, it has two examples of title dropping:
For the original title: "Ponies Make War" is the name of a book on war magic written by a famous ancestor of Twilight's.
Moriarty: And now you wish me to pay the price... because I touched your companions. Your... Children of Time.
Holmes: We Children of Time, we are weapons... weapons you fashion against yourself. You want us to be strong enough to stop you.
Doctor: No! No, not weapons! Never weapons... If you want to say you're Children of Time, you are that...
In the Lyrical Nanoha fic, ''Judgment Day's Not Coming, the title is a reference to Signum coming back time and time again, most recently after her defeat at Cypha's hands, and is the last words in the fic.
Cypha: "I killed you. You're dead. I rarely get the chance to kill someone twice."
Signum: "If you bothered to have any conception of my history, you would know what it means to be a Wolkenritter. My judgment day's not coming."
Shizuru: Being perfect or having something that is perfect are things people often strive for, but they are things that are impossible to reach. Not only is it difficult to define, but frankly, perfection is overrated. You never have to improve yourself, struggle against your weaknesses, or learn how to understand yourself or the ones you love.
Girlie, heart-shaped stickers stuck to the glass of the picture proclaiming Light to be a "darling" and a "sweetheart."
Address Unknown has Derpy give this monologue after Twilight agrees to search for a spell that will fix her eyes, despite admitting there may not be one. "You know, occasionally when Iím delivering mail I get a letter addressed to a place that doesnít exist; maybe somepony moved, or maybe somepony miswrote the address. When we get those letters, we just send them back to where they came from and move on to the next destination. There is nothing we can do in the Post Office to make that address appear. Maybe that same thing will happen with fixing my eyes. Maybe there is no answer; maybe there is no fix. It doesnít mean we canít look, but if itís not there, then itís just an 'address unknown'. If no answer exists, then I can move on without any regrets."
