Definition of velcro

A British term describing when a ball is tight on the cushion and a player sends the cue ball to hit both the object ball and the rail at nearly the same time; the object ball, ideally, stays tight to the rail and is thus "velcroed" to the rail. Inside english is often employed to achieve this effect, hitting slightly before the ball. The movement of a ball just next to the rail (but not the shot described to achieve this movement) is called hugging the rail in both the UK and the US.
