I've been in the lifestyle r/t for about 2 years, and I have yet to come across this, either with a partner or at a dungeon. I speak to everyone the same. My dom doesn't require a title. I can call him by his name or whatever I'm comfortable with which happens to be "Daddy." As far as I know, there is no standard manner of speech. It's best to ask your Master what the hell he's talking about. Is he Gorean? That's the only difference I can think of....third person speak maybe?
