52 aka 52 handblocks aka jailhouse rock aka jailhouse 52 aka jailhouse boxing aka mother dear's 52 aka jailhouse aka gansta lox (i heard this name used by a guy from l.a. it turns out to be the same thing). 52 is kind of a strange animal. the training is hard and secretive. it is rbsd all the way and has no illusions or fantasies about it. btw, kudos to the thread starter! i loved the article. it is so rbsd!
