The code set by all bro's alike that they don't:
and fight over some bitch
2.) date their fellow bros' ex's (if he's over her or not.)
3.) whatever the hell other rules they wanna add to the list.
Basically, a set definition to the "Bro's before Hoes" saying.
Trevor: Dude, are you dating Elise?
Koven: Sure am man, she's great.
Trevor: Fuck you man, that's against the Bro Code
