I had this happen to me, or something similar. I went home with a guy at the same age, and the next day they were all talking about how it was a “grunt hunt” . However, and I mean this without arrogance, I’m actually considered very attractive. I didn’t know what a grunt hunt was, and was told it was when you sleep with a pig. My and his friends were saying stay away from him, this is what he’s doing and saying, I was really shocked, his friends didn’t support him which is where I guess it differs. He’d been chasing me for quite some time.
He then kept trying to get with me again, not knowing I knew what he had said, obvs it was a no go, but I can honestly say it impacted me hugely , I would shake and hyperventilate and need to basically move away when he entered the space I was in.
It didn’t Impact me in the way I suddenly felt I was a “pig” , I didn’t loose confidence, you know when you’re attractive, and again sorry for that, but more that it was him being a complete arrogant dick, saying that he could get with the pretty girl and call her a pig , that he’d not have went near me otherwise, but I felt really , really ashamed, and everyone knew. That I’d went home with him and he told everyone the next day he only got with me as I was a pig and due to the grunt hunt thing he had going with his mates,
so I sympathise with your daughter, it was utterly horrendous for me, and 3 decades later I still feel that horror when I think on it. Which, to be clear I don’t often. She will get past this, but yes it’s horrendous and horrifying to know this shit still goes on,
