“Flags in hand, a group of wheezing scribes of questionable fitness are ‘crabbing’ their way left and right along the sideline of an indoor football pitch at St George’s Park, opulent home to the National Football Centre in Burton-on-Trent. As the verb suggests, the exercise involves shuttling sideways at speed in order to keep up with and constantly monitor play, while simultaneously providing a moving target for any projectiles that might be raining down from the crowd behind. The ability to ‘crab’ is an essential skill for any match official and one this reporter has since adopted to maximise efficiency while shopping in supermarkets that are long of aisle.” Guardian (Video)
