an abbreviation for over achiever; the person in school or work who pisses everyone off because they always have to do more than what is required, hand in assignments before they are due, they always have to be perfect, and they make everyone else look bad.
Eww, Kelly is such an O.A. She already finished the history paper that's due next week and she wrote two pages more than she needed to.
