What does throw mean in soccer?

Answer 1

A 'throw' in soccer is when the ball goes out of bounds and a player on the team opposite than the one who kicked it out must 'throw' it back in bounds. The player has to leave one foot on the ground all the way through the throw and bring both hands over the head.
