Ground out is a term commonly used in sports, mainly baseball, to describe an out where a batter hits the ball and it is caught by a fielder after it bounces on the ground. There are several synonyms that can be used in place of ground out, such as a bounce out, a worm burner, or a chopper. A bounce out refers to the ball bouncing off the ground and being caught by a fielder for the out. A worm burner is used when the ball scorches across the ground, grazing the infield dirt before reaching the outfield. A chopper is used when the ball is hit with a downward motion and bounces rapidly, making it difficult for the fielder to catch it before making the out.
