Sigmund Freud has proposed a concept called 'Penis Envy".

A bitch wanna shows off her learning competence in E&F freshman course, so she utters "Derivative", "Econometrics" in her blog, and her main language is Chinese.

Also, all females are hideous in nature. If they hate you, even you have been dead their retaliation will not cease. We can see that there is gentlemen, but there is no such thing called gentlewomen, just because females are stingy in nature.

So inductively, all females tend to be delinquent.
Since juvenile delinquency is MK Behavior,
we can just conclude that since puberty, all females are MK.
