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. One side effect of being a YuGayOh is chronic denial. Because of this the game will only be talked about to their closest friends. Because of the lack of friends the individual has the few they do will be bombarded with lectures on cards they have never heard of, and never plan to.
