bdh is a crew in South Florida that doesn't take shit form anyone and always have each other's backs. Law enforcement has classified them as a gang but that is not how the affiliates and close friends see it. They are very similar to FSU (Friends Stand United) in their beliefs and and actions they take to keep their name untarnished. Many members live the straight edge lifestyle and are firm believers in it while other members partake in drinking activities. They do not discriminate against anyone which is why the bonds they make with each other become so strong. However, if you disrespect a member there is a pretty great chance that you will get your teeth pushed in. bdh has been around for enough time to earn a not so great reputation because of their "gang-like" activities and criminal mischief.
I wouldn't talk shit to that guy if i were you. He's got bdh ties and you could wind up seriously hurt.
