1937, jook organ, from jook joint "roadhouse" (1935), Black English slang, from juke, joog "wicked, disorderly," in Gullah (the creolized English of the coastlands of South Carolina, Georgia, and northern Florida), probably from Wolof and Bambara dzug "unsavory." Said to have originated in central Florida (see "A Note on Juke," Florida Review, vol. VII, no. 3, spring 1938). The spelling with a -u- might represent a deliberate attempt to put distance between the word and its origins.
