Similar to the first definition on the page, but when you are "slamming" her from behind, you randomly throw it in her ass. When she looks around back to you to see what the hell's up, you crack her right in the side of the jaw!
Everything's going great and you both are in the zone, but then you spice things up and throw it in her ass. Due to the pain of this move, she'll definitely look back to you to see what the hell's up. Then, crack her in the jaw and tell her to keep looking forward as we're doing it! The relationship may take a downward slope after performing this on your partner!
