The word and meme “Kek” was first popularized in the World of Warcraft community, who used it as a form of LOL. However, over time it has gone through many transitions of meaning. Know Your Meme explains how it was picked up on 4chan to signify Internet trolls and people who post negative comments, designating them as citizens of the fictional country known as Kekistan.

The symbolism and design of the “Kekistan flag” was actually modeled after a German Nazi war flag, replacing the swastika with the K and vertical lines symbols and swapping the red color with green.
