E. N. I. C.
A person who thinks they know everything and is always ready to argue about it.
My cousin is an E. N. I. C. He argued with the pizza delivery guy because the cheese was wrong.
My dad is an E. N. I. C. He got into a fight with the grocery store because the bread was stale.
My friend is an E. N. I. C. She yelled at the clouds because they weren’t pink.
