CNC stands for "consensual non-consent" and is a term used in the BDSM community to describe a type of roleplay where one partner takes on the role of a predator and the other partner takes on the role of a victim who is overcome by force. It is also known as "rape play". The key feature of CNC is that it is consensual, meaning that both partners have previously negotiated and agreed to the scenario. CNC is a controversial kink that is not fitting for everyone, but some people find it cathartic and empowering.

It is important to note that CNC is not the same as actual non-consensual sex, which is a crime. CNC is a type of erotic roleplay that involves prior consent and negotiation of boundaries. The term CNC can also refer to "computer numerical control," which is an automated method of controlling motion in machines used for industrial operations such as milling, turning, and cutting.
