Head-play

Also known as "mind-play, mind games, head games, head trips, and mind-fucking." This means any kind of manipulation by the top which heightens anticipation and fear in an emotionally masochistic bottom and thus intensifies the bottom's erotic response. This includes everything from "verbal abuse" to complex scenarios that confuse or surprise the bottom into deeper "sub-space." A "mind-fuck" (deliberately misleading a partner into believing something horrible is about to happen).
