An act of aggressive sex with someone as if they had no respect for the person as an equal human being, regardless if they actually do, or not.
Hate fucking usually entails aggressive, sometimes violent, degrading, and humiliating sexual acts and behaviors perpetrated by an aggressive party onto a submissive, solely in the interest of the
aggressor's own pleasure and amusement, and without regard for the submissive party's enjoyment or well being.
Unlike rape,
hate fucking is a form of consensual sex where the submissive party has agreed (for whatever reason) to accept the treatment and behavior of the aggressor. Though unlike proper BDSM, the submissive party has not previously discussed boundaries, likes or dislikes, and doesn't necessarily enjoy all, or even any of the treatment they receive.
