honky n.

disparaging U.S. slang term for "immigrant laborer from central or Eastern Europe," 1896, probably ultimately a shortening of Hungarian, though the name was applied as well to Lithuanians, Poles, South Slavs, etc.

"cheap night club," by 1893, American English, of unknown origin. It starts to appear frequently about 1893 in newspapers in Texas and Oklahoma; a much-reprinted snippet defines it as "a particularly vicious and low-grade theater." In the Fort Worth, Texas, "Gazette" in 1889 it seems to be the name of a particular theater, and the Marshall, Texas, "Messenger" of May 27, 1892, mentions the "Honk-E-Tonk district" as "the most disreputable part of town." As a type of music played in that sort of low saloon, it is attested by 1921.
