when a group of bros live together in a house, apartment or other residence, and share in some sort of bromance. in extreme cases of bromesticity, members may have nicknames that make fun of notable historical and literary characters by replacing a syllable of their names with "bro" (such as, brostoevsky,broseph stalin, et. al.)
did you see those guys living in that house together? they're so bromestic!
