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!

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"
