rape myth

Erroneous, stereotypical, or prejudicial beliefs about sexual assaults, rapists, and rape victims, which serve to excuse sexual aggression.

Emily: Did you hear that Amber got raped after she left the bar Saturday night? That sucks..
Jack: Well she shouldn't have been drinking and she shouldn't have left with that guy.. it's her fault!
Emily: Stop buying into that rape myth, it is NEVER the victim's fault!
