When you are doing a chick doggy style. You go in like your going to grab her tits and abruptly swing your arms outwards so she falls on her face. Now start pushing her around the room into coffe tables, lamps, etc. making bulldozing sounds.

A guy who plows a plethora of women in a short amount of time

Bulldozer: whilst during anal penetration, the act of driving your partner around the room on their face.

The bull dozer is performed when a guy is hittin' some chick from the back. Once deep in the action, the guy pulls the chick's arms behind her back(so she falls face down on the bed)and pushes her.
Now from here you have some options(but not limited to): Pushing her around the bed. Ramming her head into the wall, or my personal favorite, Pushing her right off the bed!

The fat kid you follow behind at School to get through a crowd quickly.

A sex move that is a spin-off of the doggystyle postion. The male is doing it doggystyle with the female and he sweeps her arms out from under her causing her face to plow into the bed, while he holds them behind her back.

Done in doggy style position. After ejaculation, use your last thrust to break your partner's neck against the bed post.
