As I’m sure you’re aware most women truly despise another woman who uses sex to get ahead.
The absolute WORST thing any woman can call another is a slut.
I ran into that when I was a Regional Representative....and as a woman myself I certainly could have trumped everyone of those who played their hand that way. However I’m a Professional and therefore only had to bide my time and the contracts ended up in my court....they got booted.
On the insult scale for men, is the equivalent of a man calling another man a “pussy”.
