As you know, in headlights there is a line where Eminem says that his Dad "fucked them both", referring of course to himself and his mother Debbie. This line does seem harmless, but the way he says it sounds as if he is possibly implying that his dad forced sex upon him and his mom.
This isn't that bad, I mean, his Dad does seem like a bit of a scumbag so you'd assume that he'd have forced sex upon Eminem at some point in his life. However, please consider this next line. "Thank you for being my mom and my dad"...
Holy. Fuck. Debbie was Eminems dad. DEBBIE FUCKED EMINEM. That is why he's always been so angry at her, and he just lowkey admitted that she forced herself on him in a song apologizing to her.
Sick shit Em.
