An cancerous disease that starts to grow slowly in one's anus. The person in question that carries this disease feels like he/she is getting pounded in the butt from time to time. The anus will turn green and become moldy while at the same time there is also some blood loss. So far there is only 1 person diagnosed with this disease. He's the blond lord of the homosexuals, which is believed to be the cause of said disease; massive anal orgies.
