Bro Code 

The sacred code held between Bros. Its closest equivalent or counterpart is Girl Code. To break code with one of your Bros is a blasphemous, sacrilegious, and high Bro treason.

To break the code of Bro is to break the Brolific bond you might have with your Bros.

Example ~

Bro 1: "hey dudes, please don't tell my GF i came to play poker tonight, she'd be totally pissed Bro."

Bros 2 and 3: "Don't even trip man, Bro code."



An example of Bro Code being defiled:

Bro 1: "Dude! I just found out my best Bro has been coming to my apartment and fucking my girl and drinking my beer!"

Bro 2: " Thats ghey as fuck dude, you should totally beat his bitch ass."

Guy Code 

Do NOT mess with a friends crush when you know it is his crush.
If you ever find your friend messing with your crush when you even told him and he is fully aware, you are allowed to use lethal force. If the two were both drunk you are required to wait 12 hours before asking him what he did. If no good reaction was given, you are allowed to use lethal force.

Do NOT break the guy code.
