When someone try to do a stage dive but the crowd moves away (usually happens when fat people try to stage dive).
Any attempt at a stage dive or crowd surf that causes the crowd to separate as the person is still in midair.
Friend #1: Don't do it!
*Fat Guy jumps of stage*
*Crowd moves from under the fly fat guy*
*Fat Guy falls on his face*
Friend #2: Why did you try a flying moses, fat ass?
