Unfortunately we do not own the words meaning just by sheer will. SLUT is mostly derogatory unless used playful "you SLUT!" between friends.
" a picky lady" has different implications :)
I salut your slut definition. I guess that makes me one too :D
See? Now you're getting it. This is how we start owning the words. Also, I like to say that the difference between a whore and a slut is that whores do what they do for money (or other value) and because they kinda have to. Sluts do what they do because they enjoy it and aren't ashamed to. Whatever it might be. Technology, writing, music, sex... whore vs slut.
