Bondage (BD) / passive
Bondage (BD) / passive refers to a specific practice within the realm of BDSM (Bondage, Discipline, Dominance, Submission, Sadism, and Masochism), where one partner takes a passive role in being restrained or bound by the other partner for sexual pleasure or erotic play. In this context, "passive" indicates that the person being bound or restrained is the one who is receiving the action and relinquishing control to their partner.
