Sorry to resurect an old thread, I was so busy on Friday. No, Allosaurus, it wasn't Toots.
There are so many more cutting things to say to a woman than calling her c***. How about:
If she's north of 40, "God, you look so old, did you get enough sleep last night?"
If she's proud of her work, "God, you're such a loser."
If she tried a recipe, "What the **** is this shit?"
If something is wrong with a kid, "What the hell did you do?" Or "It must be from your side."
As there is no word, I think, that would make a man go apoplectic, such as the c-word, (he's heard them all before from 5-years old) the above would also apply to a woman saying them to a man. Thus the case for being decent and civilized.
