Darrell Waltrip or is he is also known "DW" is an American talking billboard that they put in the broadcast booth during Sunday NASCAR Sprint Cup Series broadcasts for Fox Sports . He is known for coining senseless phrases such as Boogity Boogity Boogity. And calling people cat. Darrell is best known though as the cause of most of your headaches by the time the race is halfway over. Before he was a broadcaster he was a race car driver who also never shut up.
