HAIC
The person who's in charge but doesn't know how to be nice. They're loud and they're always right.
My dad is HAIC. He yells at the TV and thinks he knows more than the sports commentator.
My friend's grandma is HAIC. She tells everyone what to do and doesn't listen to anyone.
My neighbor is HAIC. He thinks he's the best at everything and doesn't let anyone else speak.
