MIKE: You are a VERY good guesser, and YES you are correct, except that I don't have a step brother, I have a step sister.
A term used in rugby when a player with the ball, instead of side-stepping OUT of contact, runs straight through the defender usually resulting in hollering teammates and a semi concussed defender. Traditionally seen as a bad move in the sport but sought after by most players.
