A poorly maintained, cluttered room/living quarter where a goon/gooner spends most of his time mainly endulging in activities such as watching porn and mastrubating. A goon cave inhabitant is an individual with poor hygiene and social skills wich the state of his disgusting goon cave tends to reflect.
