Explanation:

The motion to Postpone Indefinitely is a parliamentary procedure that can only be made when a main motion is pending. It is used to kill a motion without a direct vote on its merits. It cannot be laid on the table (that's a different motion), doesn't automatically go to committee with the main motion, and is not applied to all subsidiary motions.
