Mental play - the collection of activities intended to create a psychological impact, often without a physical component.
Heavy play - indicates elements that are intense and/or carry substantial social stigma. The bulk of activities undertaken by BDSM participants would be considered heavy play or as bordering on heavy play. Examples of heavy play may include caning, suspension bondage, and erotic hypnosis.
Edge play - play that is considered especially dangerous.
Light play - consists of activities that are considered mild and/or carry little social stigma. This especially includes BDSM elements commonly practiced by "vanilla" couples, including light spanking and light bondage.
Bork - play that is considered exceptionally dangerous and in many cases well over the edge of what many would consider is acceptable risk.
Physical play - encompasses all 'kinky' activities that are carried out physically.
