Kakukery
When a cat acts like it's the king of the litter box and does its business with extra flair. Now it's used for anyone doing anything with extra flair, even if it's just eating a sandwich.
My cat did the kakukery while I was trying to sleep. I was wide awake for hours.
He did the kakukery in my mom's coffee. She was not happy.
She did the kakukery at the grocery store. The clerk asked if she was okay.
