An acronym for Bondage and Discipline, Sadism, Masochism. It is comprised of consent from the parties involved for very rough, erotic sex. It is not rape since there is consent from everyone involved. There is much role-playing involved when involved with BDSM. Gagging, choking, toys, orders given to the submissive, costumes, leather, slapping, whips, basically everything that is kinky, can be seen in a case of BDSM. It is neither abuse or assault due to consent as well.
