bootylicious (adj.)

mid-15c., bottyne "plunder taken from an enemy in war," from Old French butin "booty" (14c.), from a Germanic source akin to Middle Low German bute "exchange." It has been influenced in form and sense (toward "profit, gain," whether taken by force or not) by boot (n.2) and in form by nouns ending in -y. The meaning "female body considered as a sex object" is 1920s, African-American vernacular. As with other male sexual terms for women, its sense can shift to copulation generally or to the eroticized body parts (compare nookie, ass, etc.).

c. 1300, "delightful to the senses, pleasing in the highest degree" (implied in deliciously), from Old French delicios (Modern French délicieux), from Late Latin deliciosus "delicious, delicate," from Latin delicia (plural deliciae) "a delight, allurement, charm," from delicere "to allure, entice," from de- "away" (see de-) + lacere "to lure, entice," which is of uncertain origin.

Especially, but not exclusively, of taste. Related: Deliciously. As a name of a type of apple, attested from 1903, first grown by Jesse Hiatt of Iowa, U.S.A. Colloquial shortening delish is attested from 1920.
