A word indicating a Chinese person, possibly racist because of the word "gook" put in.
Don't ask where I got this. Even I don't know. To be honest it just came out of nowhere and I started saying it. I often use this word to refer to a Chinese person, or Chinese people (Chinagook can be plural as it sounds).
"The Chinagook want to nuke us!"
"I'm gonna be the Chinagook."
