Maarken
A Maarken is a guy who moves in and never leaves. He eats your food, takes your couch, and claims your pets as his own. He acts like your house is his and you're just a guest.
He moved in and ate all my snacks. He didn't even ask.
He took over my couch and now I have to sleep on the floor. It's not cool.
He took my dog for walks and now my dog thinks he's my dad.
