Fun Fact
The origin of “kibosh” is somewhat mysterious and hotly debated among etymologists. One theory suggests it comes from the Irish phrase “cie bais,” meaning “cap of death” (referring to a judge’s black cap worn when pronouncing a death sentence). Another theory links it to the Yiddish word “kabas,” meaning “to suppress.” Yet another suggests it might come from the word “kurbash,” a type of whip used for punishment in some Middle Eastern countries. Despite its unclear origins, “kibosh” entered English slang in the early 19th century and has been putting a stop to things ever since.
(adjective) Noisy, unruly, and difficult to control; stubbornly resistant to restraint or discipline.
The obstreperous crowd refused to disperse despite three separate announcements, their noise and defiance rising with every attempt to restore order.
Obstreperous derives from the Latin obstreperus, meaning “clamorous” or “noisy,” built from ob- (“against”) and strepere (“to make a noise” or “to rattle”). The root strepere is also the ancestor of strep in streptococcus — both words carrying the sense of something loud and disruptive making itself impossible to ignore. It entered English in the early 17th century, immediately acquiring its dual sense of both physical noisiness and the kind of willful, uncontainable defiance that produces it.
