fullbacker 

A Fullbacker is one who pushes others out of the way on a crowded dance floor at a sludgy college bar to reach the painted pole or otherwise significant ornament at the center of the dance floor.

The guy just knocked over six people! Now we can dance near this gold pole. He's a great fullbacker.
