A Gook is a derogatory term for any native yellowman of Southeast Asia or Korea. Gooks are best known for using Human Wave tactics in warfare, and owning restaurants serving the best "Hot Dog" in town. They differ from Chinks, as chinks are Chinamen.
There are 3 main species of Gook:
Southern Brown: Dog-eating South Koreans or Southern Vietnamese Paddie Farmers. Also are shitty fighters (See ARVN). Will be routed easily in battle and immediately call for American support.
American Brown (AKA Boat People): West Coast Refugee families. Have 10+ Wannabe-Gangbanger Kids and drive a Toyota Previa.
