bunch
Middle English
From Middle English bunche, bonche (“hump, swelling”), of uncertain origin. Perhaps a variant of *bunge (compare dialectal bung (“heap, grape bunch”)), from Proto-Germanic *bunkō, *bunkô, *bungǭ (“heap, crowd”), from Proto-Indo-European *bʰenǵʰ-, *bʰénǵʰus (“thick, dense, fat”). Cognates include Saterland Frisian Bunke (“bone”), West Frisian bonke (“bone, lump, bump”), Dutch bonk (“lump, bone”), Low German Bunk (“bone”), German Bunge (“tuber”), Danish bunke (“heap, pile”), Faroese bunki (“heap, pile”); Hittite [Term?] (/panku/, “total, entire”), Tocharian B pkante (“volume, fatness”), Lithuanian búožė (“knob”), Ancient Greek παχύς (pakhús, “thick”), Sanskrit बहु (bahú, “thick; much”)). Alternatively, perhaps from a variant or diminutive of bump (compare hump/hunch, lump/lunch, etc.); or from dialectal Old French bonge (“bundle”) (compare French bongeau, bonjeau, bonjot), from West Flemish bondje, diminutive of West Flemish bond (“bundle”).
bunkum
Origin
From buncombe, from “speaking to (or for) Buncombe County, North Carolina”, a county in North Carolina named for Edward Buncombe. In 1820, Felix Walker, who represented the county in the U.S. House of Representatives, rose to address the question of admitting Missouri as a free or slave state, his first attempt to speak on the subject after nearly a month of solid debate, right before the vote was to be called. To the exasperation of colleagues, he began a long and wearisome speech, explaining that he was speaking not to Congress but "to Buncombe." He was ultimately shouted down by his colleagues, though his speech was published in a Washington paper and his persistence made "buncombe" (later respelled "bunkum") a synonym for meaningless political claptrap and later for any kind of nonsense, at first only in the jargon of Washington and then in common usage.
bupkis
Origin
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.
Bur
Middle English
From Middle English burre, of unknown origin but probably from North Germanic (Scandinavian) source or from Old English byrst (“bristle”). See also burr. Compare English bristle, Danish burre (“bur, burdock”), Norwegian borre, Swedish borre, and Old Norse burst (“bristle”).
