IMO victim blaming means blaming the victim for what the perpetrator did.

Take a woman who gets really drunk alone in a dangerous place, who gets assaulted. Getting into this situation is the woman's fault. Getting assaulted, however, is not the woman's fault. The assaulter chose to assault the woman. Assaulting the woman was the attacker's fault. Putting the responsibility for the actions of the assaulter on the woman is victim blaming.
