(verb) An action executed by a girl to their boyfriend that means to be bossy, or to constantly tell someone what to do, all the time. Literally. Nothing is said that isn't an order. And those orders are expected to be followed, or the person executing those orders will flip out, usually in the most stupid ways possible. Let it be noted that as soon as the girl is able to boss their boyfriend around, they think they can boss everyone else around, too.
Person #1: "Shut up and stop doing that, or I will act like a cry baby!"
Person #2: "Are you pulling a Brook?"
