The small but ever-present population of bros at Oberlin College. They are an endangered species compared to the dominant Oberlin archetype, the Bearded Flannel, but still manage to consume more food than is proportional to their numbers. They are constantly in contact with their female counterparts, who constitute Hoberlin.

A word used to describe an extemely "down to earth" individual. Brotherman can be used simultaneously with the first name of a person in an effort to show they share a strong mutual bond. A group of cool people can be deemed brothers as they share a strong brotherly bond.
