Drill Rush
Drill Rush (formerly named the "Triple Dash") is the name of Meta Knight's Forward B attack. Seen in this screenshot and several times in videos posted outside the Dojo, Meta Knight appears to leap sideways with his blade outstretched. If he hits an enemy, he performs a combination lasting up to a good 2 seconds, knocking your opponent upward. Also, when finished, he pulls back a bit. It appears Meta Knight can also change the course of the attack, he is shown using the same attack upward, allowing it to be used as a recovery. After using the attack, Meta Knight becomes helpless. It may be derived from Kirby's Running-B move when he has the Master Ability (which he has when he uses Meta Knight's sword) ability in Kirby and the Amazing Mirror. Judging by a new video by Phanna, it is possible to cancel the ending lag of the forward b by making the end hit the edge allowing it to be virtually lag free allowing it to be used to rush opponents in such stages as batlefield. This is known as Drill Rush Cancelling.
