Bro (subculture)

Bro is a male youth subculture of "conventional guys' guys" who spend time partying in ways similar to each other. Although the popular image of bro lifestyle is associated with sports apparel and fraternities, it lacks a consistent definition. Some aspects vary regionally such as in California where it overlaps with surf culture. Oxford Dictionaries have noted that bros frequently self-identify with neologisms containing the word "bro" as a prefix or suffix.
