Nagatha
A super annoying old nag who yells at you like you're the last piece of cake and it's burnt to a crisp. Bob called Linda Belcher Nagatha Christie because she was being a royal pain in the butt.
My mom is Nagatha. She yells at me for eating cereal for dinner. Again.
My boss is Nagatha. He says my work is garbage, even though I did it right.
My pet parrot is Nagatha. It squawks at me every time I take a sip of coffee.
