Vietnamese communist-sporting people. Term dates back to the Vietnam war when US soldiers began to suffer heavy casualties against the resilient Vietnamese defenders.
Gook also is at times referred to Korean people.
That gook popped out of a hole!
John McCain: 'I hate them gooks!'
Vietnamese person: 'I may be a gook but I beat the living shit out of you'
U.S. Army: You'll kill 10 gooks for every nigger that dies in battle, but they'll keep on coming.
Gooks are excellent soldiers if you provide them with an AK-47 and white rice.
