Grab cancel

Discovered in Super Smash Bros. Melee, the Grab Cancel, also known as a Boost Grab, is the only form of L canceling that can be performed on the ground and it's a very common form of Dash attack canceling. Unlike the typical L Cancel, which has to be performed in the air just before landing on the ground from an aerial attack, the grab cancel can only be done when you do a Dash Attack. It can't be done if you do a smash attack or a jab. It doesn't cancel the lag of the attack, but it completely cancels the attack and turns it into a grab. To do this, you must Dash, press A while dashing and press L,R, or Z immediately within the first frame. This move is more useful than a Dash Attack if you want to prevent yourself from getting hit. But if you skip the first frame of the Dash Attack and then grab, then you won't do a grab cancel and you'll suffer due to the lag of the attack. If done correctly, you'll skip straight to a grab. Although this attack looks useless, leading you to think that you can just press Z to save time, the grab cancel is a very good mind game.
