also hoity toity, 1660s, "riotous behavior," from earlier highty tighty "frolicsome, flighty," perhaps an alteration and reduplication of dialectal hoyting "acting the hoyden, romping" (1590s), see hoyden. Sense of "haughty" first recorded late 1800s, probably on similarity of sound.

hoyden n.
"ill-bred, boisterous young female," 1670s; earlier "rude, boorish fellow" (1590s), of uncertain origin; perhaps from Dutch heiden "rustic, uncivilized man," from Middle Dutch heiden "heathen," from Proto-Germanic *haithinaz- (see heathen). OED points to Elizabethan hoit "indulge in riotous and noisy mirth" in Nares.
