The biggest to me is not talking about your feelings, what bothers you, mental issues, what's going on in your home etc just for the sake of "we are bros so we have to be tough". Depression, body issues, rape etc are not just "girl" stuff we swipe under the carpet.
I've been playing rugby since I was 7, I know all about this, the "bro" life and the codes that go with it.
And that sucks because we have to do better than that, we NEED to look after each other and that implies going the extra mile with your "tough looking" friends. That can spare years of alcoholism, depression, abuse in the relationships.

So yeah, the "no pink" or "the banana rule" are the "dumb" part, but really letting go and talking about what happens in your head is the most important one of all. Talking about it doesn't make you fragile. I wish some "bros" I knew realized that.
