Having never been owned, i haven't had the pleasure of being called "slave", but there have been several names i've enjoyed.
The "dirty" ones: fuckslut, anal/ass slut, cum slut, fuck puppet, hole, cunt, and whore (although i'm sure there are some i'm forgetting)
The "nice" ones: kitten/kitty, pet, girl. Only one person has called me "sweetie" and elicited a good response, and with him, i get all tingly when he says it. I don't like hearing anyone else say it - it just doesn't sound right - but he gets away with it *and* it makes me feel good. Odd how that happens...
As for being in trouble, there's usually no name-calling involved. If i've done something wrong, i simply get a command - sit, face to the floor, etc. It's actually mildly terrifying, knowing that i've been *that* bad that i've elicited that tone.
