Gook

Gook (/ˈɡuːk/ or /ˈɡʊk/) is a derogatory term for people of East and Southeast Asian descent. Its origin is unclear, but it may have originated among U.S. Marines during the Philippine–American War (1899–1902). Historically, U.S. military personnel used the word “to refer to any dark-skinned foreigner, especially a non-European or non-American.” The earliest published example is dated 1920 and notes that U.S. Marines then in Haiti used the term to refer to Haitians. It was widely used in Asia in both the Korean and Vietnamese Wars.
