Habotnic
A person so set in their ways, they’d rather die than admit they were wrong. They’re like a dog with a bone, no matter how bad it smells, they’re not letting go.
My grandpa is a habotnic. He still uses a rotary phone and thinks the internet is a scam.
My teacher called me a habotnic for wanting to wear hoodies in class.
My neighbor refused to move his car even though it was blocking my driveway.
