Consanguineous- related by blood or sharing a common ancestor
Ex: Consanguineous relationships have sent many monarchies spiraling down double helical staircases of chromosomal abnormalities and jarringly disfigured appearances. Through inbreeding, certain traits are passed down from generation to uglier generation, along with a slew of increasingly grotesque mutations that (literally) rear their ugly heads in the princes and princesses unfortunate enough to be born into these kingdoms of monetary wealth, yet genetic poverty. Take the British monarchy for example: We see crumbling biscuit teeth the color of breakfast tea, duchesses that look like the visual equivalent of the smell of a sweaty post-jog Susan Boyle eating a warm Scotch Egg in a London Taxi Cab, and dukes who might be confused for an aging Wayne Rooney desperately clinging to life in the nuclear winter depicted in the BBC TV movie Threads. These are a people that have the potential to be good-looking—see David and Victoria Beckham—but have thrown away that possibility through the weird, Alabaman desire to remain purebred. Now imagine if these consanguineous relationships started springing up in a group that is inherently bad-looking, with zero redeeming qualities: Cryptocurrency tech developers. Inbreeding in this enclave of eye-sores would select for traits such as: flaming funyun breath, carpal tunnel syndrome, and unkempt, knotty neck beards. But that’s just the physical side of the equation. On the personality side, the offspring would also be really fucking annoying. Thankfully we now have silicon humanoid AI robot women entering the picture to prevent such dev-on-dev relations.
