Jill’s reference is the Bokononism from the Cat's Cradle fictional universe While researching for his upcoming book, the narrator travels to Ilium, New York, the hometown of the late Felix Hoenikker, a co-creator of the atomic bomb and Nobel laureate physicist, to interview Hoenikker's children, coworkers, and other acquaintances. There, he learns of a substance called ice-nine, created for military use by Hoenikker and now likely in the possession of his three adult children. Eventually, a magazine assignment takes the narrator to the (fictional) Caribbean island of San Lorenzo, one of the poorest countries on Earth. On the plane ride, the narrator is surprised to see Newt and also meets the newly appointed US ambassador to San Lorenzo, who provides a comprehensive guidebook on San Lorenzo's unusual culture and history. The guidebook describes a locally influential semi-parody religious movement called Bokononism, which combines irreverent, nihilistic, and cynical observations about life and God's will; an emphasis on coincidences and serendipity; and both thoughtful and humorous sayings and rituals into a holy text called The Books of Bokonon. Bokononism is the semi-humorous religion secretly practiced by the people of San Lorenzo, which encompasses concepts unique to the novel. Many of these concepts use words from the San Lorenzan creole "dialect" of English. Many of its sacred texts, collectively called The Books of Bokonon, are written in the form of calypso songs. Bokononist rituals are equally strange or absurdist; for example, the supreme religious act consists of two worshippers rubbing the bare soles of their feet together to inspire spiritual connection.
