RACK
From BDSM Wiki
Risk-aware consensual kink (RACK, a.k.a. risk-accepted consensual kink) is an acronym used 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 thoroughly safe, sane, and consensual are permitted to be practiced.
