When two family members of the opposite gender have sex, resulting in the creation of a tyrant.

When you do it with your sibling of the opposite gender, your child will most certainly become a tyrant or live a life of suffering. Adolf Hitler was inbred, his dad fucked his niece, resulting in an incarnation of evil. Caillou is also inbred, he screams constantly at the littlest things and is just a general bitch, I mean why the fuck else would his parents names rhyme? If you do it with your cousin, there`s only a 50% chance it will be a piece of shit. Porn always features incest, somehow people find it hot, therefore, it is the fault of the porn industry that incest has become ever more prevalent! Even the bible (the biggest piece of horse shit in the galaxy) is against inbreeding!
