A very strong brotherhood, also known as the YAK. Founded in late 2008 by King YAK, Ghost YAK, OAK, Predator YAK, and Master YAK. All the members are well know for their ability to perform very hard physical and mental tasks, but there's only one thing that identifies a YAK and that's their huge penises.
