A woman so attractive you want to get pregnant to keep her.
The attractive level must surpass a desire to not have children. It will even override common sense however the woman must be a true beauty, not a decent one.
1. That Naomi Komaki is so hot I want to get her pregnant so she would have to stay with me. She's a real knock up knock out.
2. That knock up knock out is so hot I put a hole in the condom.
