mr. meeseeks 

Mr. Meeseeks is a blue humanoid character from the show Rick & Morty that poofs into existence upon pressing the button on the Meeseeks Box. Meeseeks are not born fumbling for meaning. They are created to serve a singular purpose to which they will go to any lengths to fulfill. Existence is pain to a Meeseeks.

Mr. Meeseeks #1: I'm Mr. Meeseeks, look at me!
Mr. Meeseeks #2: Hi Mr. Meeseeks, I'm Mr. Meeseeks! Look at me!
Mr. Meeseeks #1: Hi!

Messed up 

A bad thing, or an unusual thing. Also a really strange thing that’s not necessary.

“Kevin, can you please move your seat towards the very back?,” said Ms. Smith

“Yeah sure, can I sit in the front though since no one sits there and I can see the board better?,” said Kevin.

“No, I’d like you to sit in the back because that way you won’t be near your friends,” said Ms. Smith.

“But why would I sit in the back when I can’t see in the back anyways? Bro that’s just messed up,” said Kevin again.

Meeseeks 

Someone who cannot survive without constant attention from other people. Common sayings are "watch this", "look at me", "look what I can do", etc. See: Attention whore. From Rick and Morty episode "Meeseeks and Destroy", where a character named "Mr. Meeseeks" always shouts "look at me!!!"

"Can she not survive without attention? Ugh, She's such a Meeseeks"

Meese Day 

July 1st Holiday Celebration in the Loadout video game community.

This comes from the Loadout Community where a non-native english speaking player was attempting to ask about Canadian holidays and if, in fact, Canada had a day celebrating the "meese species" in chat. After some confusion it was discovered that he was asking if Canada had a day celebrating the moose. It snowballed from there and has taken over the entire community.

Meese Day was first celebrated July 1st 2013.

I'ts July 1st. Happy Meese Day!
