Edgeplay

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").

Edgeplay may involve the consequences of potential short or long-term harm or death, exemplified by activities such as breathplay (erotic asphyxiation), fire play, knife play, fear play, temperature play, wax play, consensual non-consent, and gunplay, as well as the potential increased risk of infection when the possibility of bodily fluid exchange is present, such as with cutting, bloodplay, or barebacking. Urethral sounding is also considered edgeplay because of its medical risks.

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.
