re: My buddy just slept with his buddies ex wife

It's more of a respect thing. Marriages don't just end and the feelings die when the ink dries. People need time to heal. A good friend would help in that healing, not bury his pecker in his friends wife.

How do you know the marriage and feelings haven't been dead for years and the paperwork was just a mere formality? She's not his wife. They're exes. As in not married.

This "bro code" does seem a little juvenile and high schoolish.

I think a lot of these guys preaching this "bro code" nonsense are just trying to scare suitors away from their exes because they're afraid the next guy is going to do a better job of curling her toes than they did.
