bupkis
Bupkis (noun) means (informal) Nothing at all, or something worthless.
Etymology
Borrowed before 1931 from Yiddish באָבקעס (bobkes), the plural of באָבקע (bobke, "goat or sheep dropping"), itself from באָב (bob, "bean") plus ־קע (-ke), calquing Polish bobek ("oval-shaped turd"), which ultimately goes back to Proto-Slavic *bobъ ("bean, fava bean"). It was popularised by American Jewish writer Sam Denoff in the mid-1960s show The Dick Van Dyke Show.
