Kaiseress
A queen who thinks she's the main character of a very bad movie
My cousin is the Kaiseress of her family. She walks in like she just won the lottery and everyone has to bow to her.
The pizza guy said he was the Kaiseress of cheese. He put extra pepperoni on my pizza just because.
My little brother is the Kaiseress of our bedroom. He wears a crown and tells me I'm his servant.
