What do you call a hippie's wife?

This joke is a play on words involving the state name “Mississippi” and the term “Missus,” which is a title used before an adult woman’s name or surname to indicate that she is married. The term “hippie” refers to a member of a counterculture, originally a youth movement that started in the United States during the mid-1960s and spread to other countries. Hippies were associated with a rejection of conventional values, and the term “Mississippi” sounds like “Missus Hippie” when said quickly. The joke is that the wife of a hippie would be called “Missus Hippie,” which phonetically sounds like “Mississippi.”
