Bro Code

In popular culture, the Bro Code is a friendship etiquette to be followed among men or, more specifically, among members of the bro subculture. The term was invented and popularized by Barney Stinson, a character from the television show How I Met Your Mother. Katherine Connor Martin, head of content creation at Oxford Dictionaries, recognized Stinson as "the quintessence of a certain iteration of the contemporary bro".
