There is a shot that I have witnessed a number of times, and I don't know how to do it. When I try to find out about it in books, online, or videos, etc.. I come up empty handed.

What I'm talking about is, when a guy shoots a thin cut shot at warp speed with high follow, and the cueball hits the rail at high speed but then just squats in place spinning furiously. It's a stop off a cushion. My gut tells me reverse english must be operating in the shot, but having attempted to replicate the action it is evident to me that speed and sidespin are not the only factors.

I'm perplexed. Can anyone tell me how this stop and squat action can be achieved?

Thanks in advance for any worthwhile help. Namaste.
