I don't understand it either and it scares me a little bit more. I remember once a bunch of guys were yelling, "RAPE RAPE RAPE" and laughed about it. I told them that I was uncomfortable with them and I asked as politely as I could to stop.

One guy thankfully understood but his friends started to talk about what they wanted to do with me. In front of me.

Thankfully, the one guy was bigger than the rest and got them to stop or he'd beat them up even worse.
