slump buster n. an unattractive woman sought by a man for sexual relations in order to improve his sports-playing abilities or his involuntarily inactive sex life. Etymological Note: This is a very specific sense of the more general slump buster ‘something perceived to stop a losing streak, improve sports performance, or to increase sexual activity.’ This sense’s recent popularity stems from a 1998 interview on Jim Rome’s syndicated sports talk show with Mark Grace, former first baseman for the Chicago Cubs, although the term is older than that.
