When one "Pullsa Rob"it means they are telling you something that you obviously already know. Not only does doing that make you angry, but it also makes you hate the person drastically more than you did before.
"Hey did you hear that the Colts won the SuperBowl?"
"Yes you retard. Don't ever Pull a Rob again."
