where i live, vertical surface 'leaning' has always been ok, whether that vertical surface is a wall, chain link, or goal post. dabbing is supporting yourself on a horizontal surface, whether it's the floor, a link in the fence, or the crossbar. therefore, a flat palm on a fence is fine, but once you stick your fingers in it, you're using the horizontal part for support. same applies to crossbars, or in europe, the tops of goal posts
