My parents would just turn the music up, but the problem was after a while we learned exactly what it meant every time they played Enter Sandman loud. Mum would tell us she was just vocalizing - yeah I guess that's the word.
It got to be the song of fucking in that house and after a while they knew that we knew. So they changed it up and started playing Pantera instead. Fucking Gen X strikes again.
Everybody starts as a cream pie anyway and kids are going to hear something at some point, not sure how much it matters.
