kuru
Kuru (noun) means a fatal disease of the nervous system, once seen among the Fore people of New Guinea, caused by an infectious protein and thought to spread through ritual cannibalism.
Etymology
Comes from Fore kúru, literally “trembling, shivering”. It may ultimately go back to Proto-Gorokan *kút(V) (“dangling, shaking”), if it is cognate with the reduplicated element in Yagaria gúli gúli hu- (“be loose, rattle”).
