Consensual non-consent , also called meta-consent and blanket consent, is a mutual agreement to be able to act as if consent has been waived. It is an agreement where comprehensive consent is given in advance, with the intent of it being irrevocable under most circumstances. This often occurs without foreknowledge of the exact actions planned.
Consensual non-consent is considered a show of extreme trust and understanding. It is controversial within BDSM circles, even often frowned upon due to concerns about abuse and safety. It is mainly limited to those in Owner/property and 24/7 Master/slave relationships.
In recent years the term has also been used for the practice in play sessions. In the past, the term consensual non-consent was reserved to committed relationships, while the play practice used the umbrella term of edge play. This expanded scope is contentious and the subject of acrimonious debates.
In limited parts of the online BDSM community, “consensual non-consent” is instead used to refer to rape play that includes the use of safe words. This use of the term is commonly frowned upon, especially among total power exchange lifestyle participants. Experienced practitioners of BDSM generally discourage others from using “consensual non-consent” to indicate rape play. This attitude arises from the belief that it is a miscommunication potentially leading to serious and irreparable psychological harm.
