yahoos in Culture



The crude, dirty “brutes” of the land of the Houyhnhnms in Gulliver's Travels, by Jonathan Swift. The Yahoos are irrational people and represent the worst side of humanity. By contrast, the wise and gentle Houyhnhnms, their masters, are rational horses and represent humanity at its best.


A “yahoo” is an uncouth or uncivilized person.
