The Bro Code is a set of guidelines that govern the behavior of bros. The code is primarily concerned with maintaining the bro bond, and as such, it places a great emphasis on loyalty, trust, and respect. Some of the key tenets of the Bro Code include never hitting on a bro's sister, never stealing a bro's girlfriend, and always having each other's back in a fight.
While the Bro Code is primarily an unwritten set of rules, there are a few books that purport to document the code in all its bro-tastic glory. One such book is The Bro Code by Barney Stinson, which was published in 2008. The book is a humorous take on the code, and as such, it is not meant to be taken too seriously. However, it does provide some insights into thegeneral principles that underlie the Bro Code.
Another book that claims to document the Bro Code is The Bro Code for Parents by Lew Bryson. This book was published in 2009, and it provides advice for fathers on how to raise their sons to be good bros. While the book is not as light-hearted as Stinson's offering, it does provide a more serious look at the code and its importance in maintaining brotherly bonds.
