A Fredstad
A Fredstad is when you screw your family like a bunch of rats in a trash can. It’s the worst kind of inbreeding, and it’s named after a kid who got bonked by his dad for years.
My uncle married his niece. That’s a Fredstad if I ever saw one.
My cousin had a baby with his aunt. Classic Fredstad vibes.
My grandma had a fling with my grandpa. That’s a Fredstad right there.
