bupkis

Etymology

Borrowed prior to 1931 from Yiddish באָבקעס (bobkes), plural of באָבקע (bobke, “goat or sheep dropping”), from באָב (bob, “bean”) + ־קע (-ke) calquing Polish bobek (“oval-shaped turd”), ultimately from Proto-Slavic *bobъ (“bean, fava bean”). Popularized by American Jewish writer Sam Denoff in mid-1960s The Dick Van Dyke Show.
