R-E-T-R-R-F: it's a politer way of saying retard when you're trying to call someone it in public..

it also is a describing word, it means awesome or ultra sexual..

RETRRF is also a disease known to people who think other people are mad at other people. It's VERY common, and the only cure is to ASK PEOPLE WHAT'S WRONG..you know, not over facebook or the internet, or through text or phone.. BUT IN PERSON!!!!!!!!!!!!!!!!!!!
