https://en.wikipedia.org/wiki/Kek_(mythology)
Kek is the deification of the concept of primordial darkness.
In relation to the 2016 United States presidential election, individuals associated with online message boards, such as 4chan, noted a similarity between Kek and the character Pepe the Frog. This, combined with the frequent use of the term "kek" as a popular stand-in for the internet slang "lol", which was often paired with images of Pepe, resulted in a resurgence of interest in the ancient deity.
