A trick play formerly used in American football before it was banned. In a fumblerooski, the quarterback sets the ball on the ground after the snap, and leads defenders away. If successful, a single unnoticed lineman picks up the ball and barrels down the field.

This play has been banned in all levels of American football; last run in 1992, by the Nebraska Cornhuskers, the team largely responsible for its popularity.
1984 Orange Bowl, Nebraska v Miami: down 17-0, famous Nebraska coach and current congressman Tom Osborne called a successful fumblerooski in which a lineman rumbled 20 yards for a score, taking the defense and spectators completely by surprise.
