BORK
Edge play is dangerous; do not try this at home!
Balls Out Risky Kink (BORK) is an acronym used to describe a philosophical view that is permissive of exceptionally risky sexual behaviors. 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.
Parameters
BORK indicates a type of play that there is a substantial risk of serious injury under even cautious conditions.
BORK differs from typical edge play in that the term edge play more commonly references types of play that can have catastrophic results in the cases of equipment failure or improper technique, but that in edge play those risks are mostly mitigated by equipment maintenance and proper technique, where as with BORK even with proper equipment maintenance and proper technique a large and substantial risk is still present.
An example of BORK might include inserting a knife into an orifice or using a whip crack to slice a stick from the mouth of a bottom, where a simple involuntary sneeze from the bottom could result in a trip the emergency room, permanent injury, or death.
Controversy
BORK methods of play are generally considered patently unsafe, even by world class experts that can perform these techniques flawlessly and repeatedly.
Best Practices
Best Practices indicate to always be very well informed about any risk you are taking, if you are not informed of the potential dangers you cannot meaningfully consent.
