The purpose of this study was to gain a better understanding of sexually aggressive behavior through the examination of humor appreciation among male undergraduates. As compared to nonaggressive males, sexually aggressive males showed a significantly greater appreciation for humor which negatively stereotyped females, portrayed prejudicial views of rape-and rape victims, and contained content related to male sex drive and virility. Differences in humor appreciation were also found for males with high sex drive. Additional findings included correlations between aggressive drive and sexually aggressive status, as well as between sex drive and likelihood to rape.
