Rape sex occurs when a rapist is in the act of rape, and the rapee (the person being raped) in turn rapes the rapist.
Simply put:
Person A rapes Person B. However, Person B starts to rape Person A - effectively canceling out the rape (by making it legal and consented sex).

Rape sex is similar to a theorem in a subject like algebra. If John rapes Susy, but Susy in turn rapes John than they really didn't rape at all; they had perfectly consented to sex. All the rape cancels.

Modern mathematics say if you have the equation: m/m
That two m's cancel out, leaving only 1.
In context of rape sex, the equation would be: rape(sex)/rape(sex)
The problem being that both rape and sex would cancel out, leaving the number 1. Obviously this proves the mathematical theory of procreation (aka sex) as the number 1 will be the child created by sex.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.
