Slave

Within some adult consensual BDSM relationships, slave is a role term for a person who chooses an especially structured or service-oriented form of submission. It can carry strong emotional and historical weight, so it should never be assigned casually or used to suggest that another person has lost their basic rights or agency.

The people using the term need a precise shared definition of what it means in their relationship. Even in a deeply negotiated Dom/Sub dynamic, consent remains ongoing and boundaries remain enforceable.
