Gook (/ˈɡuːk/ or /ˈɡʊk/) is a derogatory term for people of East and Southeast Asian descent.[1] Its origin is unclear, but it may have originated among U.S. Marines during the Philippine–American War (1899–1913).[2][3] Historically, U.S. military personnel used the word “to refer to any dark-skinned foreigner, especially a non-European or non-American.” [4][5][6] The earliest published example is dated 1920 and notes that U.S. Marines then in Haiti used the term to refer to Haitians.[7] It was widely used in Asia in both the Korean and Vietnamese Wars.
