A word that sounds like a swear word but is only used when you’re too tired to be mad.

My mom said, 'You're the Nagguh of the house!' because I left my socks on the floor.

My teacher said, 'You're the Nagguh of the test!' because I drew a cat on my paper.

My friend said, 'You're the Nagguh of the lunch table!' because I ate all the pizza.
