A study explored the social acceptability that accompanies the expression of sexual slang. The study of gender differences in language use is nothing new. Previous research has indicated that men and women differ in their use of tentative language, topic selection, control techniques, and conversational style. However, this research has examined differences due to male and female biological sex, and has not examined differences due to psychological gender. Subjects, 49 male and 92 female undergraduate students enrolled in an introductory communication course at a large midwestern university, completed the Social Acceptability of Language Scale and the Bem Sex-Role Inventory. Results indicated that, for the most part, neither biological sex nor psychological gender accounted for differences in the social acceptability of sexual slang. Findings suggest that men and women are moving toward a universal use of sexual slang. (Contains 48 references and 1 table of data.) (Author/RS)
