Macob
A person who does their job so good it makes other people look like they failed a test. They know everything and don’t care if people hate them for it. They are the king of their field and don’t plan on letting anyone else take the throne.
My boss is a Macob. He knows more about spreadsheets than I know about my ex.
That chef is a Macob. He can cook a whole meal with one hand and a burnt toast with the other.
My math teacher is a Macob. She can solve equations faster than I can finish my lunch.
