The problem with "bro" culture is its narcissistic conformism. I guess they are really looking for an excuse to behave badly. They know they are being assholes, so they manufacture a social environment in which they are encouraged to be assholes. So listen, bros: If you want to get drunk, and hit on chicks, that's your choice. But don't give in to peer pressure, and don't pressure your mates. Just be yourself.
