A set of useless, bullshit rules that guys use to govern and bully around their friends, guys or girls.

examples of breaking the bro code:

1. you slept with a girl a friend used to like

2. you ask a girl out that you once saw an aquaintance out with a month before

3. you are friends with someone your friend hates
Guy 1: "what did i do wrong?"

Guy 2: "hello!? you fucking broke the bro code rule #27."

Guy 3: "oh, duh, i checked out a girl that you once liked. i am so sorry."
