To pull a Herdy is to be completely against "The Boys" and be a big bitch. Also pulling a Herdy refers to loving a single girl even when she dumps your pathetic ass. Another defintion is to update your status every 10 minutes all regarding the same mutt. Herdy's almost always have the first name "Brandon".
