 Yahoo (Gulliver's Travels)

In Jonathan Swift's satirical novel "Gulliver's Travels," Yahoos are a fictional race of beings that resemble humans but are depicted as primitive, base, and brutish creatures. They embody the worst aspects of humanity, such as greed, irrationality, and savagery, and are presented as a stark contrast to the more rational and civilized Houyhnhnms, who are intelligent horses that govern their society through reason and virtue.
