To me this skirts dangerously close to territory that should be left alone. The subjective issue in humiliation is that not every sub is humiliated by the same thing. I may thrill at receiving my Masters golden nectar all over my face and body and another sub would never think of every allowing this to happen to her. Some subs crave the humiliation of name calling - others may find it devastating to their self-esteem and wonder what their Master truly thinks of them if he can call them such things.
If you, as a sub, have a burning need for a certain type of humiliation, respectfully ask for it and, as stated above, communicate at all times. If the attempt is made and it crashes and burns, be sure to talk about it afterwards, too, to make doubly sure you know how Master feels about you and no negative impact occurs.
