etymonline
boobs (n.)
"breasts," 1929, U.S. slang, probably from much older term boobies (late 17c.), related to 17c. bubby; perhaps ultimately from Latin pupa, literally "little girl," hence, in child-talk, "breast." Or else it is a natural formation in English (compare French poupe "teat," German dialectal Bubbi, etc.).
