In inline skating, the move one ends up making with their arms if one doesn't properly bend his or her knees. This ultimately futile attempt to regain balance inevitably results in the perpetrator landing on his or her rear.
When I was rollerblading the other day, I hit a piece of gravel that sent my balance off. I started doing the windmill of death and ended up falling on my butt.
