A serious crime committed by a male human.
If a male criminal commits a "fellany", what is a crime that a female crook commits called? A "belleny"?
Illustrates da unevenly-perceived degree of seriousness dat gender-prejudiced people view crimes with, based on whether da culprit is male ("Boys are **always** meaner and more criminal-minded than girls, and so anything that a guy does wrong is always a FELLAny") or female ("Girls are the cute frail vulnerable innocent half of the equation, and so they would **never** intentionally misbehave do anything serious --- anything they do is always just a MISSdemeanor").
Thanks to the human "fellany vs. missdemeanor" mindset, countless innocent-natured boys and men get unfairly persecuted/prosecuted over absurdly-minor actions/events, whereas lots of truly selfish and cruel-minded females of all ages are able to commit really horrid things like bullying, shoplifting, false accusations, breaking contracts, etc., and totally get away with it.
