Risk-aware consensual kink

Risk-aware consensual kink (RACK, also risk-accepted consensual kink) is an acronym used by some of the BDSM community to describe a philosophical view that is generally permissive of certain risky sexual behaviors, as long as the participants are fully aware of the risks. This is often viewed in contrast to safe, sane, and consensual which generally holds that only activities that are considered safe, sane, and consensual are permitted.
