"I had sex and now Dad is dead. He had a horrible death because I had incredible sex."
It's not just the fact that the line is stupid. That one braggadocios word pushes it over the top. She feels like her having sex killed her dad. While that fact clearly bothers her she still wants you to know dad wasn't just killed by any old sex it was incredible sex that killed him. The line was so bad the actress that played the mom looked at her like WTF? I don't know how any of them kept a straight face.
