A nemin is the most engaged or knowledgeable member of a fandom, they know ever bit of lore and probably have spreadsheets and journals to keep all their thoughts straight. Sometimes despite (or perhaps because of) their constant engagement and eternal knowledge they will hate the very the very thing they have put months of their life towards understanding.
