Snowplow

Fucking someone in the doggy position wildly enough that they lose their hand position and fall off the bed, face first.

Kristi and I were fucking like we had just barely met. We were really charged up and going at it; next thing you know, she snowplowed onto the floor, me on top of her. I broke her toe, was very sad. She and her husband went to Vegas the next day and she had crutches. :(
