The Odd Couple Slob is a term used to describe the character of OSCAR Madison, played by Jack Lemmon in the 1968 film adaptation of Neil Simon's play of the same name. OSCAR is a slovenly sportswriter who lives in a messy apartment and is the polar opposite of his neat-freak roommate, Felix Unger, played by Walter Matthau. The term 'OSCAR Madison Slob' has become synonymous with the character and is often used to describe someone who is disorganized and untidy.
