late 14c., depraven, "corrupt, lead astray, pervert," from Old French depraver "to pervert; accuse" (14c.) and directly from Latin depravare "distort, disfigure;" figuratively "to pervert, seduce, corrupt," from de- "completely" (see de-) + pravus "crooked," which is of unknown etymology. Related: Depraved; depraving.
1560s, "act of becoming bad or worse;" 1570s, "depraved or corrupt quality or character," from Latin depravationem (nominative depravatio) "a perverting, distorting, corrupting," noun of action from past-participle stem of depravare "distort, disfigure; pervert, seduce, corrupt" (see deprave).
mid-14c., "deprave morally, pervert from good to bad;" late 14c., "contaminate, impair the purity of; seduce or violate (a woman); debase or render impure (a language) by alterations or innovations; influence by a bribe or other wrong motive," from Latin corruptus, past participle of corrumpere "to destroy; spoil," figuratively "corrupt, seduce, bribe" (see corrupt (adj.)).
Intransitive sense of "putrefy, change from a sound to a putrid state" is from late 14c. Related: Corrupted; corrupting. In Middle English also corrumpen (mid-14c., along with corrumpcioun), from Old French corompre, from Latin corumpere.
also hoochie-coochie, hootchy kootchy, "erotic suggestive women's dance" (involving a lot of hip-grinding), 1898, of obscure origin, usually associated, without evidence, with the Chicago world's fair of 1893 and belly-dancer Little Egypt (who might not even have been there), but the word itself is attested from 1890, as the stage name of minstrel singer "Hoochy-Coochy Rice," and the chorus of the popular minstrel song "The Ham-Fat Man" (by 1856; see ham (n.2)) contains the nonsense phrase "Hoochee, kouchee, kouchee."
To-day, however, in place of the danse du ventre or the coochie-coochie we have the loop-the-loop or the razzle-dazzle, which latter, while not exactly edifying at least do not serve to deprave public taste. ["The Redemption of 'Old Coney,'" in Broadway Magazine, April 1904]
