Bro culture is a subculture of young people (originally young men, hence "brother culture")[1] who spend time partying with others like themselves.[2] Although the original image of the bro lifestyle is associated with sports apparel and fraternities, it lacks a consistent definition. Most aspects vary regionally, such as in California, where it overlaps with surf culture.[3] Oxford Dictionaries have noted that bros frequently self-identify with neologisms containing the word "bro" as a prefix or suffix.
