Actually, Ghis, some use slut/ho/bitch/cuntfaceassmuncher... as endearing phrases. I do it all the time. =]
I understand people using them to make fun of FRIENDS but not speaking of someone you don't know.
It's like I'm sitting at a bar and call the waitress "yo bitch, can I get my drink asap, you ho?": it's just rude.
Yeah, but in the way she's using it, she's talking about her like a friend, so it's okay.
