"a tramp," 1889, Western U.S., of unknown origin. Barnhart compares early 19c. English dialectal hawbuck "lout, clumsy fellow, country bumpkin." Or possibly from ho, boy, a workers' call on late 19c. western U.S. railroads. Facetious formation hobohemia, "community or life of hobos," is from 1923 (see bohemian).
