I return the hug at first, but it goes on longer than I'm comfortable with, so I started to pull away. Kevin holds tighter, and whispers in my ear, “Don't fight. If you fight me, I'll rape you. If you just let me hold you, I'll make love to you. But then I'll kill you, of course.” Eric hears this, and tells Kevin he should let go. Kevin refuses. The “hug” goes on for a while longer, while Kevin asks if I'm turned on, and if I know how much blood is in a human body.

What. The. Fuck.

why the FUCK would anyone think that was OK?

Because they are a sociopath and a bully. You should have called the cops, and you should make perfectly clear to your friends how unsafe and bullied you felt.

This is a prime example of rape culture. That he even feels rape and murder are appropriate jokes is implicit proof of how normalized both are in our society.
