A 2013 tumblr April Fool's Day prank for which thousands of tumblr users changed their icon to the same photo of Misha Collins and endlessly reblogged said photo and manipulated thousands of gifs, soundfiles, posters, photos and screencaps to contain reference to the OVERLORD. All tumblr users not affiliated to the Misha's minions or Supernatural fandom were extremely alarmed but unable to escape.
Misha #1: ALL HAIL THE OVERLORD
Misha #2: PRAISE BE TO MISHA
Misha #3: REBLOG FELLOW MINIONS
Misha #4: REBLOG ALL THE MISHA
Misha #5: THE MISHAPOCALYPSE IS NIGH
Random blogger: HELP WHAT IS THIS I CANNOT ESCAPE
Random blogger #2: I HAVE BEEN CONVERTED VERY FUN APOCALYPSE 10/10 WOULD RECOMMEND

Worse than the apocalypse

The whole world is taken over by Misha Collins and his fans
Teacher: Dd you do your homework?
Misha Collins Fan: No, It was the Mishapocalypse

Meanwhile a non Misha Collins fan probably wouldnt make it to school because they are too busy cowering, scared in a corner.

The event on Aprils 1st, 2013, when all the Mishamigos (and Misha's Minions) changed their icon/avatar to a specific picture of Misha. This has been spread to many websites, and has elicited an interesting reaction from non-mishas. On this day, every Minion and Mishamigo is Misha, and must refer to each other as such. Gender (or lack of) and race do not matter.
I am Misha.

You are misha.

We are all Misha.

Misha: Greetings, Misha.
Misha: Good day, Misha.
Misha: Do you have news on the Mishapocalypse, Misha?
Misha: Yes, in fact, I do, Misha. It is going well. We have converted several billion people/accounts to Misha.
Misha: Good. Continue with the good work, Misha.

The Mishapocalypse is the day where tumblr users unite as one -- one Misha.

Their brave hearts reblog and like every post.

Some don't like it, and they unfollow.

But, us Mishas stick together --

Through the thick and thin.

Embrace the Misha.

Feel the Misha.
Become one with the Misha!
Tumblr User 1: Hey, have you heard about the Mishapocalypse?

Tumblr User 2: Yeah dude that's so annoying

Tumblr User 1: We're not friends bye

We are all Misha.

You are Misha, I am Misha.

We are all Misha, except for Misha.

The Mishapocalypse is neigh. Which side of history will you be on?
"Reblog this if you're a Misha, I want to follow you"

"What's up with the Mishapocalypse?"

"Don't question it, just join us."
