An intensely complicated sex move involving three or more people, three of which must be the same gender. The skookum involves at least one occasion of anal. A variety of roles are to be played by the skookers. The first is someone who pretends to be a wild animal, usually a wolf or a bear. The second takes the role of Lou Gehrig. The third skooker eats large volumes of food during the ordeal, usually in the form of subway sandwiches or chicken burritos. However, because the skookum may involve more people, it is not limited to only these types of roles. The skookum lasts hours, and frequently continues long into the night. Journey's "Don't Stop Believing" is the optimal song to skook to.
Lou, Bill, and Yanni spent all of last night doing the skookum.
