BC (Broken Cock) syndrome is a genetic disorder mainly found in men who are considered to be pussies. An example of a pussy is a man who rides in the passenger seat of his own car just because he "doesn't feel like driving". It is specifically when your boyfriend cannot perform in the bedroom since his dick hurts every time he gets hard and is too much of a bitch to get it looked at by a doctor.
Fuck, not again Brian, you really need to get your dick checked out in case you have BC syndrome.
Oh no, I hope I don't have BC syndrome... Oh wait, I'm not a bitch so that isn't possible.
