Origin

Old English botm, of Germanic origin; related to Dutch bodem 'bottom, ground' and German Boden 'ground, earth'.

  • booty from Late Middle English:

    The original core meaning of booty was ‘to distribute’. Victors in war divided the booty stolen from an enemy among themselves. The modern American word meaning ‘a person's bottom or buttocks’ is unconnected. It is probably an alteration of botty (late 19th century) in the same sense, itself an alteration of bottom, an Old English word used for the buttocks since the late 18th century. If someone urges you to shake your booty, they want you to dance energetically. A sexy woman has been bootylicious since 1994, although the word was popularized by the single of the same name by Destiny's Child in 2001.
