I feel for you dude. Just tell her it was recommended by some dudes on the Internet and it's unbelievably funny. Sure there's some "adult" content, but I just ignore that part, Mom.
I actually had the playlist playing in the car a while back and my young daughter liked the music and looked it up... (yep, that happened...)
She was like, "Dad, that music you were listening to, it's totally from some x-rated game". And I was like, "Wow, what a surprise", and she was like, "Phew, I thought you might be playing it!".
I don't yet have the kinda relationship with my kid that
Casmyr has with his dad...
