ExFurry is a YTMND user that is now deleted.
Despite this user falling into obscurity, it has been discovered in 2015 that ExFurry is the absolute originator of the I'm going to post this every day until you like it fad, which was popularized by DougFukkie around 2009. Becuase it was recently realized that ExFurry was the originator of a fad that many give credit to DougFukkie for inventing, this is why we sometimes use the name ExFukkie to refer to DougFukkie, and sometimes DougFurry.
