A B-Unit is an all-male social group from the "burbs" (hence the "B") that collectively excels at all aspects of life.\n\nThe definition is based on the elite social and sporting group from southern Canada. They are known internationally for their dominance in waterpolo, hockey, mountain biking, academics and football.\n> Yo Marty, those guys in the B-Unit have 4.0s, have hot girlfriends, and play varsity sports.
