Is it normal black people talking promiscuity

So I have been working a temp position and I am a white dude while 90% of everyone else is black. I know rap and hip hop songs talk about sexual promiscuity but the other day this one chick was talking about how she's going to go to Vegas and have sex with as many guys as she could. She said she'll have Tom on Tuesday, Derrick on Wednesday, Antoine on Thursday, etc etc. She said what happens in Vegas stays in Vegas. Then she said people are gonna be like "damn! You a St. Louis rat!"

She then later was talking about how she's possessive of her men when she's in a relationship and how she'll be peeking out the window making sure no one's coming to take her man and cooking him food and so on.

Honestly, I just felt like I wanted to throw up. To see someone have such a lack of conscience about talking like that is disturbing. I had a white/slightly native american friend I grew up with and we reconnected as adults whose goal was to have sex with over 200 women in his life. I had to stop being his friend.

I'm just wondering if all black chicks talk like this.
