Sexual Perversity in Chicago is a play written by
David Mamet that examines the sex lives of two men and two women in the 1970s. The play is filled with profanity and regional
jargon that reflects the working-class language of
Chicago. The characters' relationships become hindered by the caustic nature of their words, as much of the dialogue includes insults and arguments. The play presents "intimate relationships [as] minefields of buried fears and misunderstandings".
