Not a true bro. Someone who acts like a bro and pretends to bro out, but in reality they are just posing. They remain sober and leave their boys hangin for unbrolike activities.
Why isn't David drinking? He's sober and being the biggest poser bro tonight.
Noah's left us hangin to be with his bitch again. What a poser bro.
