@tanzanite the term "gook" comes from the sino-Korean term for America "Migook" (cognate with Quốc Mỹ; literally "beautiful country"), which the US soldiers misinterpreted as them saying "me gook".
Also, "dink" is a made-up slur; I cannot find anything on it outside of Wikipedia.
Also, gook is for Koreans, not Vietnamese
Get your slurs right
