Adjective meaning "poorly equipped, makeshift" is 1905, American English, from the sense of something held together only with haywire, particularly said to be from use of the stuff in New England lumber camps for jury-rigging and makeshift purposes, so that hay wire outfit became the "contemptuous term for loggers with poor logging equipment" [Bryant, "Logging," 1913].

c. 1300, name of a game at dice, from Old French hasard, hasart "game of chance played with dice," also "a throw of six in dice" (12c.), of uncertain origin. Possibly from Spanish azar "an unfortunate card or throw at dice," which is said to be from Arabic az-zahr (for al-zahr) "the die." But this is doubtful because of the absence of zahr in classical Arabic dictionaries. Klein suggests Arabic yasara "he played at dice;" Arabic -s- regularly becomes Spanish -z-. The -d was added in French through confusion with the native suffix -ard. Sense evolved in French to "chances in gambling," then "chances in life."

"brutal initiation, act of abusing a newcomer," 1848, said to be a college word ("This word is used at Harvard College, to express the treatment which Freshmen sometimes receive from the higher classes, and especially from the Sophomores" -- "Collection of College Words and Customs," Boston, 1851), but perhaps originally nautical; see haze (v.).ETD hazing (n.).2
