Knock Up Knock Out

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.

donkey punch knock out

When you are fucking a chick doggystyle, donkey punch yourself, knocking yourself out. Going for the double knockout, fall face first into the back of the chicks head knocking her out, while still inside her you both fall to the floor.

"Louis and Tara both have concussions from that donkey punch knock out they performed lastnight."

Knock it out

In the most basic of explanations, it means to cause a sex-induced coma. The goal is to fuck someone so well, that they fall to sleep and are late for work on a Monday when it's only Saturday.

MAN CALLING HIS GIRLFRIEND: "I hope you got another sick day, cause I'm about to knock it out."

GIRLFRIEND: "I'm on my way!" (doing 100mph)
