look up any word, like tribbing:
 
1.
to lose the will to resist and engage in sexual intercourse with someone who is obsessed or has an unhealthy attachment to you.

similarly any sexual act willingly undertaken that creates instant and overwhelming remorse can be deemed 'antirape'
Anika stalked me for ages and sent me that chewbacca toy she dipped in her vagina so eventually I caved and it was total antirape

In the Game of Rape, the antirape cards are usually jokers. They are the only cards with the power to stop a rape.
If a player plays the antirape card on a rape before the rapist can finish his/her rape combo, the rapist's turn ends prematurely and the antirapist gains control.

The antirape cannot be played on Captain America or the DM Card.
Didn't think I was going to be able to antirape your rape, did you bitch?!

The act of having sexual intercourse with another being when said being is drunk and cannot consent to the sexual act but obviously would have wanted it had they been sober; essentially a good deed.
Dude did he rape you last night?

No, I didn't agree because I was too drunk but I would have wanted it.

Ohhhh. So it was anti-rape then?
