Calling someone a "Dunn" or "Adam Dunn" is a reference to former MLB player Adam Dunn who is known for having the second most strikeouts in baseball history. Therefore a "Dunn" is usually someone who strikes out a lot in different aspects of life, usually when it comes to girls.
-Shit did Ryan dunn it with that freshman girl again?
-Yeah man he's Adam Dunn what did you expect? He struck out swinging. I heard she thinks he's a creep.
