the act of rolling on the
grass in a soccer game to waste time. This motion (not technique) is performed by players to make the referee believe that a foul has been committed or that they are injured. Most referees consequently give precious amounts of late-game time for these "grassrollers" to gather themselves up. It is completely unsportsmanlike and
annoying. Most frequently used by
Arab countries (top 5 best countries at GR'ing: Qatar, Bahrain, Oman, Saudi Arabia, UAE and Syria (tie)), and the grassrolling is usually performed against the team of the Islamic Republic of
Iran.
