Meteor canceling

Meteor canceling is the process of breaking the momentum of a meteor smash that hits between the angles of 240 and 300 degrees. This is usually performed by jumping or using an up special move to cancel the vertical momentous gain that the foe receives. Attempting to meteor cancel before the 9th frame of knockback will result in the inability to meteor cancel for 10 more frames. Prior to v0.9b, instead of meteor cancelling at the 9th frame, it is on the 10th frame

Spikes cannot be meteor cancelled; the momentum from the spike ends on its own. However, some still use them interchangeably as if they were the same. Stage spikes, at the current moment,  also cannot be meteor canceled.
