Roll After Dark

Humiliation, degradation

Degradation, being talked down to, or made to feel small on purpose.

Why people do it
Being talked down to, on purpose, with permission, reaches something praise cannot. Done right it is one of the most intense things on this list and it needs no equipment at all.
Smallest way in
Agree three sentences you may say and one subject that is off. Then use one of them. This is the practice most improved by scripting and most damaged by improvisation.
What to watch
This is the kind of play that follows people home. Never touch the things that are actually true and actually sore — body, family, work, money — unless you have explicitly agreed to. Aftercare here is not optional, and the debrief matters more than in anything physical.
In the planner
53 different things carry this tag, and switching it off removes every one of them. The mildest of them sits at easy.
