Edgeplay
（重定向自Edge play）
In BDSM, edgeplay is a subjective term for those types of activity (either sexual or mental manipulation) that may be considered to be challenging the conventional or traditional "S.S.C." (safe, sane and consensual) creed; if one is aware of the risks and consequences then the activity(ies) would be considered RACK (Risk-Aware Consensual Kink).
