Habotnic
A person who won’t budge unless you throw them out of their own house. They’re like a cat who won’t leave even when you’re trying to clean the litter box.
My grandpa is a habotnic. He still thinks the mailman is stealing his letters.
My sister called me a habotnic for thinking I could beat her at video games.
My neighbor won’t move his car even though it’s been blocking my driveway for years.
