Maarken
A Maarken is a man who just shows up and doesn't leave. He eats your food, takes your couch, and claims your pets as his own. He's like a human version of a dog who marks his territory.
He showed up at my house and didn't leave for three days. He ate my last sandwich.
He took my couch and now I have to sleep on the floor. It's not fair.
He took my dog for walks and now my dog thinks he's my brother.
