Who is Tiny Cooper from Will Grayson, Will Grayson and what is their importance?

Tiny is a high school student at Evanston and Will’s childhood best friend. He is a comically large, gay football player, who is also the president of the school’s GSA. During the events of the novel, he directs and stars in a play that he wrote about his life, first called Tiny Dancer, and then renamed Hold Me Closer.
