Numerous memes have spread through the site, some original and others finding their way from... that one site. Important to note about Tumblr and memes though - because of the sites' self-awareness, memes become old quickly and anyone using them after they've gotten "old" will be trashedviolently.
Rule #1 of Tumblr: always reblog the creator.
Alternatively, Rule #1: Do not speak of Tumblr outside of Tumblr.
One of the more popular posts is a gif from the show The Walking Dead, where one of the characters undergoes a brain scan as they became infected. Someone incorrectly stated that the gif was an MRI scan of a person's brain releasing endorphins as they die, calling it "tragically beautiful".
There's similar games done with things like horse dildos, claiming that it's a photo of an African-American burn victim (it's hard to see and looks like a pale arm with splashes of pigment on it). ...Yeah.
MapCrunch. Users would use it to be "teleported" anywhere in the world and would then chronicle their adventures in finding the nearest airport.
"Listen here, cum-slut", after a user posted an extremely angry reaction to a set of .gifs from the movie Jack and Jill, showing a CGI cockatoo getting drenched in a chocolate fountain. The user had no idea this was fake, and got hysterical about animal abuse and how the bird 'probably died, and was opening its mouth to scream', ect.
Once upon a time, someone coined the term YOLOnote you only live once. Not long afterwards, Tumblr grabbed the ball and never stopped running.
"MAGIC ANON!" In the site's roleplaying community, people will occasionally post anonymously in characters' ask boxes to declare that "Magic Anon" has caused some random effect to occur. Could be anything from a minor event to possibly even full-blown transformation. Roleplayers usually humor magic anons by playing along but have the power to deny them if they wish. The length of a magic anon's effect depends either on the anon or the roleplayer.
A gold star with "you tried" written inside it in Comic Sans, and its many variations, to be used as reaction images.
"It was a social experiment." Originated when Cole Sprouse wrote this in his final post before deleting his Tumblr, though it was popular on LiveJournal as a troll justification, as well. Usually used to denote - you guessed it - trolling.
A popular response is to reblog with a picture from Boku No Pico (Particularly the box art, which features Pico in a speedo and goggles), accompanied by the line "Did someone say Swimming Anime?"
Gifs of certain scene, with text over their eyes to represent a fandom reaction.
A picture with text next to it that says "People who (insert what they dislike people doing/saying)." Followed by reblogs that slowly remove words while keeping the same picture and eventually ends up as just "People".

Ah, the scalene triangle.
The Tumblr Code: Calling out "I like your shoelaces!" in person as a covert way of identifying fellow Tumblr users. There's a response, of course.
Similarly, there was "Can you give me directions to an Olive Garden?", used in the same manner due to the example quotes in the Quotes page.
"Nobody's perf-", followed by an image of someone as an exception to the rule of nobody being perfect.
"Do you love the color of the sky?" *scroll for infinity, then something interesting at the very end*
This was a particularly interesting example of Deader Than Disco and Forced Meme. The original post itself was only popular for a short time before a majority of people thought it was annoying and clogged up their dashes. Many parodies were made, but the derivatives and complaints were more seen than anything else, many people hadn't even seen the original until it fell out of favor.
Posting pictures of meat in hopes of finding people who comments on it with disgust. If such an event occurs, you've "found the vegan."

"Bitch i might be" to answer basically any question.
Comic Sans in general; find a humorous image a Tumblr user created, preferably a spoof of something, and it's highly likely that any text added will be in Comic Sans.
Shock over the Yahoo! acquisition, including joking about other purchasers (such as Monobear and Doug Dimmadome), and calling Marissa Mayer their new "mommy"
Collages of nightblogger posts with the caption "this is what yahoo paid $1.1 billion for"
The Sink Fandom. "SNK" Is a common abbreviation that people use to tag Attack on Titan (with the Japanese name of the series being Shingeki No Kyojin), resulting in a post that basically said (paraphrased) "You people with your SNK fandom, I've got something better: the SINK fandom!". Thus, "Sink Fandom" is a tag full of pretty or interesting sinks.
A related meme is for people to reply to questions about one "SNK" by answering with things about the other, far olderSNK (born mainly out of people growing disgruntled with Titan fans who simply can't abbreviate the series to AOT.)

It originally started with humanizations of Earth and Jupiter but warped into using all the planets.

He marked everything—including cheese and sauce—as none except for the beef, which he requested on the left side, and got a baked crust with with pieces of beef sprinkled on the left side. Naturally, when Tumblr caught word, they ate it up.
