SlutWalk is a transnational movement calling for an end to rape culture, including victim blaming and slut shaming of sexual assault victims. Participants protest against explaining or excusing rape by referring to any aspect of a woman's appearance. The rallies began on April 3, 2011, in Toronto, Ontario, Canada, after a Toronto Police officer suggested that "women should avoid dressing like sluts" as a precaution against sexual assault. Subsequent rallies have occurred globally.
