In BDSM, edgeplay is a subjective term for activity (sexual or mentally manipulative) that may challenge the conventional safe, sane and consensual ("SSC") scheme; if one is aware of the risks and consequences and is willing to accept them, then the activity is considered risk-aware consensual kink ("RACK").
In the mid-1990s, the Living in Leather convention did not have discussion on ageplay, salirophilia or scat because, at the time, they were considered too extreme for consensual activity. By 2000, some considered them to be within the scope of edgeplay.[1]
