My friend talked about wanting to grab a guy's balls

One day me and a close friend were out shopping. I can't remember how the topic came up but she said "I've always wanted to grab a guy by the balls and go like this" and had her hand in a grabbing motion and twisted her hand around. We'd been friends for a long time and other than a playful nut tap, never heard her bring up anything like that.

I awkwardly laughed and gulped and went to cover my balls. "Don't worry" she said. "I wouldn't do that to you. I meant if a guy was harassing me or annoying the hell out of me." I was so shocked and she changed the subject but I still have that grabbing and twisting motion in my mind lol. I wouldn't dare bring it up or try to get her to grab my balls, too shy and I know she'd be weirded out. It was a long time ago and we aren't as close as we used to be, but besides her, never heard a woman actually saying something like that.
