boobs Look up boobs at Dictionary.com
"breasts," 1929, U.S. slang, probably from much older term boobies (late 17c.), related to 17c. bubby, perhaps ultimately from L. puppa, lit. "little girl," hence, in child-talk, "breast," or a natural formation in English (cf. Fr. poupe "teat," Ger. dial. Bubbi, etc.).
