Tumblr's Law

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??

Tumblr Sexyman 

A male character who goes viral on Tumblr for perceived attractiveness based on an established formula. Usually white, tall, dresses fancy and is evil or has a ‘dark side.’ Though the character can be non human or non human and anthrofied to fit the said formula. Most of the time, said character isn’t really as attractive as Tumblr weirdly makes him out to be.
Ex: “Sans is literally just a magic skeleton, I have no idea how he turned into a Tumblr Sexyman.”

Tumblr Sexyman 

The Tumblr Sexyman is a male character that goes viral on tumblr typically being:
White, fit, tall, in a suit or formally dressed and being evil or having a dark side.

If the character is non human such as Bill Cipher (from Gravity Falls) or Tony the talking clock (from Don’t Hug Me I’m Scared) they would often draw them as human form.

The Tumblr Sexyman craze began with a character called the Once-ler (from The Lorax) as you can see he has the characteristics of the tumblr sexyman
(Also btw they ship the Once-ler with... the Once-ler weird right?)

A notable character is Alastor (from Hazbin Hotel) infamously known for looking like he was specifically designed to be a sexyman then actually being one.

If you want to know more characters that count as a Tumblr Sexyman there is a sexypedia for all the characters.
Person 1: Frank from subway surfers kinda hot
Person 2: He’s literally just some basic Tumblr Sexyman

Tumblr social justice activist 

A tumblr blogger that may blame men, white people, skinny people, attractive people, and almost anything for oppressing them and making the world a worse place. Does not seem to engage in any activity that relates to any actual activism, prefers to judge everyone else loudly and type up possibly fictional stories about how they were 'oppressed' that day. Age demographic varies from teens to middle aged adults, mostly females.

Warning: May go off on rage fueled rants about perceived privilege among other things. Do not attempt to reason with it, logic has given way to just feelings alone.
So I went to hang out with an old friend of mine recently and things were going well until I mentioned one of my favorite TV shows, Wilfred. She started going off about how Jason Gann (Wilfred) was sexist and supported rape. I was obviously shocked and in disbelief. She started going on and on about rape culture, white privilege, male privilege, and it was all she could talk about for quite a while. Then she asked me if I had a Tumblr. It turns out that she turned into what some people called a "Tumblr social justice activist".
