Rough Body Play
Rough body play is similar to play fighting but differs in that the Top and the bottom tend to have more of a power exchange dynamic as the Bottom will not actively work against this play happening and behave like a recipient to the activity instead of a very active participant.
Often connected to primal roles, common applications include punching, kicking, holds, breath play, hair pulling and other forms of generally rough activities. This kind of play can include sexual activity, but is sometimes also combined with rope bondage or other forms of play where the recipient tends to be moved around and controlled by the applicant.
Note that careful negotiation and consent is important with any rough play. See Risk Aware Consensual Kink.
