A person who is obsessed by the childrens card game, Yugioh. They are hated by anyone who is normal, and because of this their obsession is usually hidden. Friends of YuGayOh's who are not fans of the show are alienated by the person, mainly because of the abuse the person gets from enjoying a childrens card game, when being over fifteen years old.
