Rare Pepe is the "name" of the meme as far as the subject specific custom pepe images/shops go.
But I still can't believe that there is a research paper out there where there is a section which describes the researcher's "collection" of rare pepe memes with visual aide samples.
I can't believe that a presidential candidate prominently featured a page on their website attacking a stupid internet meme. I think the Aztecs fudged their calculations somehow, and it was really supposed to be 2016...
