When someone is way too thin, borderline anorexic, just like all the popular tumblr girls.
-Did you see that girl over there, she looks so good.
-Yeah, she's just Tumblr skinny, all clothes look good on her.

A scientific term. Tumblr's Law states that when a Tumblr user directly mentions or implies that a joke is funny, the joke is no longer funny. This can be commonly done through saying that a meme is hilarious, but can also be completed through such an action as laughing.

When a Tumblr User (commonly self-identified by a person with an active Tumblr account) laughs at something that could be considered humorous, every living being within a 5 mile radius instantly stops feeling joy for a short time. After this event, the joke is no longer funny, and it can no longer be referenced.

The only potential Tumblr Users then have for humor is in creating jokes, but hopefully it is not attempted on Tumblr.
(doge meme)
Tumblr User: this is so funny I have been laughing for 30 minutes and crying and shitting my pants.
Intelligent person: You just enabled Tumblr's Law on Doge, wtf??

Characters (mostly main protagonists/antagonists from indie franchises) that are sexualized and simped on by a bunch of LGBTQ+ kids from tumblr.

Examples like:
Baldi - Baldi’s Basics
The Onceler - The Lorax
Bill Cypher - Gravity Falls
Black Hat - Villainous
Bendy - Bendy and the Ink Machine
Sans - Undertale

(chances of your character being a tumblr daddy can increase if your character wears a comically long top hat.)

The place where woketards, neo-feminists (Misandry advocates), rabid stans, "anti-racists" (They're often racist towards whites. The hypocrisy...), SJWs, mental illness glorification advocates and people obsessed with sexuality meet to share their madness through blogging and reblogging. As someone in this online dictionary said, this website is the world's first digital mental asylum.
Dyl: What is Tumblr?
Phyl: That website is where the social rejects group up and unleash their madness.
Dyl: So more like of a containment vessel?
Phyl: Yes.

It's an interesting website, though it's one that libtards try to gain dominion when it comes to political correctness. The Cabbie Homicide author came to there and did a piece called "No One Understands Chicago" as he examines former Cradle of Filth backing vocalist Sarah Jezebel Deva. He points out she should better educate herself in social studies and enroll in a psychology class to give her material more venom. The username of his tumblr is under his short name and real last name to show readers of his anthologies a bit where he came from before he was published as he has some rather in depth blogs. The post invoked a one sided twitter war where he kept his cool and she retorted with "I bet you talk to care bears." The tweet had him cracking up because she modeled her lyrical output more akin to Nu Metal than her Symphonic Metal contemporaries. The blog revealed some aspects about the 9/11 attacks as they're not an inside job as German magazine, Der Spiegel, chronicled with the English translation of their full length report titled "Inside 9/11: What Really Happened" as he bought the VampireFreaks admin this book as commentators were calling him a Conspiracy Theorist from the information this magazine pointed out. It's quite handy for Conservative bloggers as they can use youtube documentaries for additional venom to their in depth blog entries.
Tumblr is noted for a unique presentation of a write up for the lead singer of Bloodgood's reading of Edgar Allan Poe The Tell-Tale Heart and a presentation speaking about how one editor chose The Monkey's Paw for his most personal anthology project. It's also noted for noting the debate of KenHam and BillNye as a similar exchange happened between The Cabbie Homicide writer and "Dr." Kent Hovind's son as it was played up almost akin to his first science fiction story as he was known on VampireFreaks as.
